First, I'd suggest reading the
FAQ. There's lots of good stuff there.
That said, where to start depends on your comfort level. As a wimp, I started in 0.02/0.04 and actually worked my way up. It sounds like you're way ahead of me, so that's probably a bad idea. If you're interested in using bonuses, Paradise and Party would be the best places to start. Since you're beginning, I wouldn't go above 0.50/1 initially.
You've started on the right track. Limit and NL are very different games. Keep studying SSH, reading and replying to posts here, and starting out with some hands at a level you're comfortable with.
Oh, and a good starting hand guide is crucial. I use
this one.
Good luck!
