Some templates require certain things, like creature type, but lots of them stack.
I would indeed suggest Half-Ogre, the Savage Species one.
If you're into this sort of thing, Bear Warrior is really cool. It's in Complete Warrior. Frenzied Berserker gets mad strength but if you play by the rules you might end up killing your buddies. Also in Complete Warrior.
All things considered, if you don't want your character to get too tricky then a regular pounce Barbarian is totally fine.
