There is a 264 belt that drops from trash in ICC. Depending on your gold that might be a good upgrade for your resto (even for dps its nice). However the belt is imo the best first upgrade from frost badges. Since other pieces can drop in VoA.

Don't go for the cape, there is a very nice pvp cape that you can buy from honor. Same for the neck. An alternative is to use the frost emblems of some slaves to buy saronite, and get you crafted items for your main dps, resto or tank (depending if you plan to raid on one).
