Rin's gems are also the product of the accumulated knowledge of the entire Tohsaka family.? Not just powerful, its an old magic as well.
What the
hell are you talking about?
The only gem that Rin has that contains magical energy from anyone but her is the pendant she uses to heal Shirou, and even then all that matters is that there's a lot of it, not that it's "old".
By that description, Arturia uses the force of her swing to accelerate light.
Well, could you please explain to those of us who actually understand basic physics how Saber could accelerate something which is only able to travel at one speed?
And don't say "she accelerates it to go faster than the speed of light", because that's not
possible. Physics simply does not work that way, and if you're going to ignore physics then you can't use physically meaningful words like "accelerate" any more....
That's a false interpretation of what it means. I believe that what it is
actually saying is that it accelerates the prana up to the speed of light (which is
almost as absurd).

Also, strictly speaking, Rin's gems aren't a spell. A-rank or otherwise. They are a storage device for magical power, so that she can tap into enough instantly in order to cast A-rank mysteries.
Actually, IIRC she stores actual spells in them (because she is limited by her own circuit capacity if she tries to draw the prana out and use it to perform a spell herself). The only exception to that (as far as I know) is the pendant. Although, she may be able to draw prana out of them for the purpose of using it for a spell.

In Heaven's Feel, Shirou wasn't able to fully utilize Archer's UBW because he'd given up on the idea that was the core belief in order to save Sakura.
Erm, no, that's simply not true. He couldn't use it simply because he's not Archer, and his life and mentality is very different. It had nothing
specifically to do with giving up on his ideal (which, honestly, he never did
anyway, because last time I checked "save everybody" doesn't mean "murder an entirely innocent girl in cold blood when she is still potentially saveable"). UBW Shirou could not use Archer's UBW any more than HF Shirou could (you can tell that by the fact that their Reality Marbles look very different).

There are possible ways around every defense. You can hit hard enough or exploit some weakness or something. But really don't think GB's follow a path to someone's heart gives it tactical thinking.
It doesn't "follow a path to someone's heart". The minute Gae Bolg is activated, it has
already hit the heart. All that remains is for the world to make up some plausible story for
why it hit the heart. It cannot be blocked, full stop.
Besides, it can be stopped by Rho Aias according to that, which only defends from one direction. If it had the tactical thinking you're giving it, it would just go around.
Rho Aias defends against the
thrown version of Gae Bolg (which lacks the same "certain hit" ability), and further it can only do so because it has the concept of preventing all ranged attacks from hitting.

So what it boils down to is whether Gae Bolg's reverse casualty needs time to activate. What I mean by that is if Gae Bolg's "you're heart's been pierced" side of the equation is instantaneous after the invocation of the technique, or if it is just a really, really fast action that precedes "I thrust my spear". If it's the later then I can understand your side. However, if it is the previous, then I don't see how he can calculate, even if it's faster then the speed of light, something that's already occurred.
It
must be "instantaneous", because if it were not then Fragarach would be able to defeat it. As soon as Lancer has invoked the technique, the spear has already hit, with no exceptions. Even reversing time and killing Lancer the instant before he attacked (which is what Fragarach does) couldn't stop it.
