1. A poke that is raidibg can be used in anything but TLR, so you're good
2. Gallade pretty much needs Reflect if its going to be of any use support-wise (Light Screen is nice, but besides Hyper Beam, neither of them really have special moves, and even then, it doesn't see much use). It should also get more Fighting-type moves than Close Combat, and Ice Punch would also be nice.
3. Bisharp is fine, no problems with him.
