Help playing NL live for the first time?

[jively]

So, I've been playing poker for a year and a half. I've won at $0.50/$1 online, and won at $3/6 and $4/8 live. I switched to NL maybe 6 months ago. I'm winning up to NL50 ($0.25/$0.50 blinds), but don't have a huge number of hands. I'm excited but nervous in trying $1/2 NL live. I have questions about buyins and counting the pot.

My total bankroll is about $2,500. I brought $600 to the casino last time to play either $6/12 limit or $1/2 NL. (I ended up playing 10 hours and lost just $29 in 6/12.) Do you think $600 is reasonable to bring to play 1/2 NL for the first time?

At a place like Borgata, where the buyin range is $60 to $300, what do you think of a $150 buyin? I want to balance being somewhat deep vs. a possible weak-tightedness I might feel playing for my stack. If I build my stack from $150 to $300, how bad is it to get up and switch to another table, buying in for $150 again?

Finally, what are suggestions on building the skill of counting the pot? In limit, I count bets as suggested in SSHE. I think I will probably be OK with it; I am pretty good at rounding and adding in my head, but just looking for suggestions.

Also, at this level, is it time to wait for the action to be on me to look at my cards? In limit, if not in the blinds, I look as soon as I get them; in the blinds, I wait for someone to open so I can chop blind if necessary.

Thanks,

P.S. The 6/12 was pretty loose, and I was up and down, but just ended down. I was thinking of trying 10/20 limit as well. Which game should be most profitable? 6/12, 10/20, or 1/2 NL?
