Another 'problem': Villain goes allin every single hand. You hold QQ and are last to act. Call? How about 22? AQ? K8?
I tend to play higher stakes games and let's say that I hold my own.

Re your "problem" - if it is just you against him then of course you call him with QQ if he is a regluar all-in pusher. You'd also call with any pair as if he doesn't have a pair you are favourite.

They key to these scenarios is the number of opponents - I think this is what is not being fully appreciated.
