PT Help please

i play NL Hold Em--primarily on party and some on Prima.

I want to be able to view my opponents stats on the tables I am playing on( I am planning on adding a few more tables instead of moving up).

Is there any software that helps to locate the juiciest tables?

Of course, i am also interested in reviewing my stats after my sessions. Since I have never done any stat tracking before, I am sure my game has a leak or two and i would like to find them.

What do I need? Is there anything I need a heads up about before using the software? I am terrible with computers, so dont worry about boring me with any basics.

I really appreciate any help or advice you guys can give.
