Online poker tools

I've been playing for approx two years and feel that my game has peaked. I'm an avid student of the game and want to advance my level of play. I'm reading about tools available to track your hands, get instant hand odds, monitor your win ratio's, ect. Can anyone recommend software that is legit, and works in conjunction with Party Poker.

I once purchased a membership to Poker Prophecy and Party Poker threatened to shut down my account if I used it again. So please be sure that recommendations will work at Party. Thank you.
