No limit cash games

Hey gents,
I mainly spend my time playing no limit tournaments, but over the last few weeks i have enjoyed greater success playing no limit cash/ring games.
i mainly play these games conservatively only really entering with solid values, however i was wondering if anyone could advice me on any books/sites/threads that i could read upon to adjust my general play from tournament poker to cash games so i can improve further.
I already have harrington's books and follow his conservative approach for cash games but am interested to find out what else might be useful.
Any advice or comments will be greatly appreciated.
Thankyou
