So, how do I start?

[Double E]

Situation: I started playing low-limit (1-4-8-8) casino poker in 1999. It took about a year to learn enough to turn from loser to winner. I played from 2000 until 2002, then basically quit playing - too much other stuff to do, not enough time.

The poker bug bit me again lately, and then I noticed SSH was out! I'm re-reading it now, but I see several holes in my game; I think I'm weak-ish tight, good enough to beat bad players for about a SB per hour, but missing out on a bunch more $$$, and throwing my $$$ to the occasional expert player.

Naturally, I checked out the 2+2 forum, and I see that internet hold em is commonplace. So - how do I start?

1. What places are available; what reliable reviews on them are available?

2. What's all this bonus stuff? (Looks like enough to turn a break-even player into a winner, and hand a winner a nice extra cushion.)

3. What tools do I need? Obviously, pokertracker software seems to be the standard. I went to their website, but- how does it work?

4. Anything else I'm missing?
