I am beginning to get back into internet poker again after a brief hiatus. Anyways, I have been building my br at Doyle's Room in the cash games and want to take 250 of it over to pokerstars soon solely for the tournies. With this br what sized buy tournies should I play? I really want to play the deep stacks and shootout tournies. Thanks in advance..

If by "bankroll" you mean that if you lose it you will walk away from tourneys and not fund anymore out of cash game winnings or personal funds, then I wouldnt go beyond $11 freezeouts.

Most people would not be that strict, though, and redeposit if they thought they were playing well and just on the bad side of variance, in which case you might start out at $22s and drop to $11s when the br got below $175 or so.
