holdem game types

[gringoloco]

Hi
I am new at the game. My question is - there seems to be 3 types of games

$1/$2
Pot Limit
No Limit
Are all three of these types of games normally available in live casino play, i.e. Miami, Las Vegas, Calif, etc.?

Am I correct?
At any rate is there anyone that can direct me to a site that will explain how to bet/betting rules and the different strategy in these 3 types of games
Thanks

Theres also 1-3 style limits. Which means blinds are 1, and bets can be made as 1,2, or 3....Same with other style such as 2-5 etc......
