That made me laugh "Learn limit next week" I've been learning limit for 4 years now

( I know what you meant).
First Read this on buying into Limit games:
Buy-ins (Bankroll Spinoff).
But You should really try the .05/.10 tables first, or if thats a little high (I think you should double the Bankroll reqs if you are new to a game) try the peeny games. This will at least get you used to the structure of the game.
Just remember the difference between LImit and NL. Limit is about making a whole bunch of +EV plays, folding, raising etc... NL is about making the more rare large +EV move. Thats why there are a few different (correct) ways to approach NL. In Limit, given ana average table, there is really only one way to play the game, and thats tight and super aggressive. You can't use your stack against somebody, Odds are key in Limit
