I'll let the big guys speak of the worthiness of the species for a bench (I don't know much about that wood, but, IIRC, it's like red oak). I'd say right now though, it probably needs to dry some more. At 8/4, I'd think the wood is still pretty wet (the center). If it can be moved in to a conditioned or dry (air) area for about 4-12 more months, it'll probably be pretty dry by then.
If I did remember correctly though, to use it as a countertop, you'll have to make sure you seal it properly. Those pores would make an excellent breeding ground for all sorts of nasty things.
