never played NL, Advice please

[Radio]

Im considering a move from small stakes limit to small staked NL or POT limit holdem, But iv only ever played limit, so where do i begin? Im going to start at the micro limits and work my way up but what books should i buy and also What are the starting hand requirements when playing NL or PL compaired to limit?. I normaly use the tight starting hand chart from SSH when playing limit is it the same for NL/PL and how big should the pre-flp raises be ect?
