$50NL at Full Tilt - Good place to start?

[NoSetNoBet]

Perhaps I should have asked this question BEFORE I made my deposit the other day...

I have been playing poker pretty consistently for several years now, but mostly in my local brick n mortar casinos. I played $3-6 limit for a couple years, then switched to NL a couple years ago when it became popular and they started spreading it in my area (San Fran Bay Area). My online play up until this point has been limited to nano-micro limits on Stars, mostly sit n go's. I've finally decided to take the plunge and play more seriously online for a few reasons:

1. I want to start playing in games appropriate for my bankroll, and build from there. With a roll of a little over $1000 right now, I really can't play in the weird 100NL games they spread here (weird because they do fixed $100 buy-in, three $2 blinds, and $4 minimum to open). The action can be pretty amazing though. Bu I have to play online to find the stakes I need to start out.

2. I want to use poker tracker and actually track my own stats and bankroll, mostly to find out if I'm really as good as I think I am (probably not), and start improving holes in my game.

3. The obvious benefits of online play: convenience, availability, etc.

So there is my "brief" and exciting background, here are my main questions:

1. Given my bankroll, I understand that I should be playing at around $50NL. Is this correct?

2. After doing hardly any research, I deposited $400 at Full Tilt and started playing there, mostly because of the 100% deposit bonus. Is this a "good" site for my level? Are any others much better?

3. If I'm looking for loose/juicy tables, what should I look for? Is it simply the higher players-to-flop percentage the better?

Any help would be appreciated. I apologize if these questions are too general and have been answered elsewhere. I like to think I'm pretty unique and important, but I'm often reminded that this is not the case...

Thanks!
