off the top of my head, apple have stopped signing iOS5 so you may have missed your chance. I'd stay on 4.3.3 for the time being as it's jailbreakable. It shouldn't* be too long for a jailbreak.
probably 5.0.1 is no different from 5.0 to jailbreak if one exists for iPad2...so i think it would not matter. but if you must keep your jb, suggest to stay on 4.3.3.
