Be sure to get all vendor pets and put on all horde tabards before you go alliance!
also sludge caked throwing weps is BiS isn't it? other than that idk
I thought I read somewhere thrown weapons are being taken out in MoP... Up to you if you wanna do the quest for them. Although they are not ideal for a rogue you may wanna do the quest for the gloves of unmitigated badassery in Azshara. Also be sure to do your horde side quest for your argas ring. You'll be able to do it again on alliance side to get another ring.
