Now, this one I might not be so helpful at.
First, I cannot strongly stress enough how useful the BillyCon script was when I focused on grinding my BillyCon stats.
I believe <a href='http://www.animecubed.com/billy/forum/viewtopic.php?f=33&t=14583' target='_blank' rel='nofollow'>this</a> is the script in question. If not, it should still be useful.
Second, I've mostly seen Rocking as a reward stat in the lower, pale-golden colored panels with music-themed titles.
For the most part, I reccomend: get the BillyCon Awesome tool on level 3, and settle in for a long, long, long session of grinding. This won't be done quickly, even if you devote that, the most efficient pre-strategized playstyle imaginable, and four +10 Flow Boosters per Con.
As for specific panels to gain specific stats...The panel arrangement varies by Con, from what I understand, so there are a lot. Bear with me on this.
First, I strongly reccomend checking the wiki pages on the subject.
The <a href='http://bvs.wikidot.com/billycon' target='_blank' rel='nofollow'>main page</a> is mostly useful as ageneral reference, though it details which stats are affected by the Last-Minute Bargain, at the end of the Con, which you might want to think about leaving con-money for. There are Dealer's Room items that grant XP, but you can usually make more in an equivalent timeframe at panels if you're careful and keep your stats (sleep, stink, nom) near peak.
<a href='http://bvs.wikidot.com/billycon:wander' target='_blank' rel='nofollow'>Wander,</a> as the name suggests, handles the various rewards from Wandering, as well as the modifiers that enable possible rewards. It requires time, sleep, and/or Flow, and it can vary with penalties instead of rewards, or useless ones for your current condition or purposes, but it's still something to keep in mind: you tend to have either too many of various stats, or too little, and if you're properly set up for grinding, it's usually the former, at which point a few good wanders can net you anywhere from 15-100 XP per, with a total of up to several hundred (give or take a thousand). It's more likely you'll fall into the 15-45XP range, if you want to grind stats for main events like the VGT or Cosplay, but it'll still be something, and every little bit helps.
Now, <a href='http://bvs.wikidot.com/billycon:events' target='_blank' rel='nofollow'>Events</a> is probably the closest tool to the information you wanted. It's a bit large, but that's because there's a lot of events/panels, and there are multiple bits of information and text with them for the wiki-makers to quote. If the script I provide doesn't work out, or you can't/won't use scripts, you'll need to reference the table here quite a bit. It should give you a fairly accurate idea of what the rewards are for each panel, allowing you to use them and the schedule to plot out an effective day.
I reccomend, as general strategy, pick the lower options when setting up the Con (Con Hotel, Own Room, Backstage Pass). It'll cost you money, but the rewards will be useful in preparing you for each days' events, which leeds to advice number two:
Don't take the overnight panels and stay up. The overnight panels can give some fairly appealing rewards, but the loss of overnight room bonuses aren't worth it, on average.
Next, keep three food, two extra clothes, and a couple items. I reccomend Giant Foam Hand and either Sunglasses or Handy Notebook, all from the Dealer's Room, the either-or depending on your playstyle preferences. You can use the Food multiple times a day for no time & for free, so you usually end up using them all either one one day, or over the course of the full Con. The Extra Clothes, however, can only be used once per day to remove accumulated Stink, and depending on your success, you can usually manage it well enough on either the first or third day to go without. The last few items are more generally useful for additional XP.
Now, big events. Cosplay, Video Game Tourney, Rave, Billy Idol. If your stats are low enough you want to grind, they might not be high enough for these, and you have to play through the first day (and most of the second) a certain way if you want to improve your chances of winning/maxing these contests, and a different way if you want to build your skills, which is fastest (though it might be more accurate to say 'least slow,') with regular Panels, in the long run.
However, the events usually give you a semi-decent amount of XP in a couple core stats no matter your condition, which can be a reliable way to build levels if you're willing to take the longer view, and Billy Idol grants +6 Sleep and +1 Cool no matter what, which could be useful for either the Rave or a few end-of-day panels. It's all a question of time vs. reliability.
Finally, if you can start it, but haven't already, I strongly reccomend playing Glowslinging in the background. I didn't, choosing to ignore it to focus on con-building until I could switch from Intent Observation 3 to Dramatic Battler 3, or accumulate enough awesome to use both; and more importantly, switch to using +Duel Boosters rather then +Flow.
That was a major mistake. Even if I was limited to one low-level, fumbling, usually losing duel each day, I would be so much further along in Glowslinging then I am now, as that one duel a day would have added up to a considerable amount, over the seven months it took me to get most of my BillyCon stats to level 4. I might even be done with Glowslinging, and into the 11-Prong Seal, or possibly Hero's Quest by now, if I hadn't limited myself to 'Best Possible or Nothing.'
And yes, this really will take a while, even precisely planned.
I'm sorry I'm not bigger on specifics, but I hope this will be of some use.
EDIT: Whoops. Forgot the first thing I responded on was how to improve your Glowslinging play. My bad. Still, even if you can't place enough Awesome for both and whatever else you like to have a bonus in, focus on the grind of BillyCon and resign yourself to a still stretched out Glowslinging build.
