yes. you can run 33's.
as for what tire to go with...will you be using it as a daily driver? will you be driving mostly on freeway or city streets? do you care about how quiet it rides or how smooth it rides? do you want mud tires that will last long or wear out quickly?
if you want a good mud tire that will last long and be quiet and smooth on the road, go with bfg mud terrains.
if you want serious off road use and dont care about shitty on road quality, go with supper swampers, they are the best off road performance for a decent price
