You can flog most of them. Keep a couple of the more expensive types -beljurils, rogue stones cos they come in handy on a few side-quests. In general itll be obvious what you need.

Oh, and a hint - if you want to sell something but dont know if youll need it again, sell it to a shop and remember which one. That way you get the money and can get the item back if neccesary. Or you can keep it in a handy container, I use the tables in Waukeens Promenade.
