6 max NL

I've got about 100k hands at full ring PL (mostly .1/.25), and am interested in trying 6 max NL and PL.

Questions:

1. Can I add a second set of P.Tracker auto rate rules without replacing my full ring auto rate rules?

2. Can anyone recommend a good, comprehensive introduction to playing 6 max (starting hands, strategy PF and post flop (threads, or elsewhere)?

Thanks.
