Well... the first two pages (set 1) are not much you guys don't know yet, since they're describing Ninjutsu, Taijutsu and Genjutsu. Here's the details I find relevant, at least:
-Ninjutsu Advantages: the user can defeat a stronger opponent, and also attack from range. Disadvantages: Depending on the jutsu, it may be hard to generate the exact amount of chakra. The seal order may also be complex and demand time. (So most strong jutsu, in theory, can be disrupted by surprising the user.)
-Taijiutsu doesn't use chakra. No, seriously. You don't need chakra to use taijutsu. Instead of transforming your energy into chakra, you immediately convert it into your attacks, more or less. Advantages: since it doesn't use chakra, you use all your stamina and it's easier to learn. Disadvantages: It's hard to attack from a range and advanced techniques may exhaust greatly the user.
-Genjutsu: it's just hypnosis that you can cast over many people. Disadvantages: Prolonged use will injure the user and it's difficult to damage the target with it.
On the second set, Juinjutsu are described as 'curses that imprison the mind or body of the target': use a seal to control their power or actions. Orochimaru's is described to stimulate Sasuke's evil intentions as he uses it, which, you know, duh. Fuuinjutsu, on the other hand, is described as 'seals out-of-control power to restore order', and it's specific to 'confine, annul, or stop the target from using a specific skill'. Nothing on using seals for storing shit. The book describes a bit what makes a technique be considered 'forbidden': either it'll cause damage to the user (Taiju Kage Bunshin, Souja Sousai, or Urarenge) or it's against the laws of nature (Kuchiyose, Edotensei).
On Kekkei Genkai, on the third set, we have a general description of it and a specific point: there are 'no rules' regarding the awakening of one. Even if both parents have them, their kid might not be born with one, or vice-versa. It's also not possible to control when it'll awaken or not.
Page 14's text is as follows:
1-Village Symbol (duh)
2-Character Name
3-Ninja Rank (if the ninja is a renegade, retired or it's a civilian, there's nothing)
4-Stats
5-Power Summary Data or such, divided in 'Average Stats' - that is, how strong the ninja is taking all stats in account - Latent Potential - presence of a Kekkei Genkai or power that wasn't included on the above - and Luck - relative evaluation of their luck, which may be crucial at some point.
6-Profile 1 (basic character details)
7-Profile 2 (backstory)
You guys owe me for this. Someone should write me something.
