I agree with Kagato's suggestions bar a few exceptions...
Weapon: This depends on if you are at max rank, which I assume you aren't since you just hit 50. If it is a slow process to rank up, you may want to get a Sgt. Axe or Moogle/Ifrit (you should get experience with these fights anyways) to act as your interim weapon until Lt. Axe.
DD Belt: I'd go with Veteran's Field Belt or Flame Sash if available
DD Boots: It's not much of a difference, but if you aren't at cap for STR or VIT, I'd go with Cobalt Sollerets or Explorer's Sabatons. Most of WAR's important WS's already have high crit rates, so I find crit stuff is a little lacking.
DD/Tank Hands: At first, Cobalt Mitt Gaunts are ok, but you should look into Felt Bracers with STR since as Churchill said, they can be used on your other classes too. If you only care about WAR, Cobalt is fine.
