Limit Hold 'em Perfection

[Sparks]

I purchased a poker statistic tracking program and have a question. For mid limit hold e'm play, are there ideal stats to shoot for regarding pre-flop betting, agression, calling/folding to steal raises, percentage of won hands when seeing the flop, etc? Are these a matter of opinion or are there generally agreed upon "perfect stats" that one should strive to obtain?

Comments and/or links to relevent threads appreciated.
