Fortunately for you, there will be a brand new LIMIT video posted on this site within the hour. It's tailored to 6 max, but you may still get some useful tips out of it, as I talk a good bit about the differences between NL and limit play.
As for your buy in, as long as you can reload whenever you need to, it doesn't really matter. But I think $100 should be plenty for a 1/2 game. That will hold you.
Of course, none of this matters anyway, since you're oging to be going deep in the tourney. GL!
