Looks good to me. Just remember that Reflect only covers 3 mons in a Raid, and since we're trying to keep Gallade's threat far below the others, I'm pretty sure it will be ok if Gallade doesn't get covered
Ok, I don't have many UC, but I'll buy Reflect, Drain Punch, and Helping Hand. Is that good? Also if you don't mind waiting a little I'm almost done a battle with Gallade in it, and if I can claim those prizes I'll also be able to buy Ice Punch and Will-O-Wisp.
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.
