+1 Park tool site is excellent. There really is not a need to buy an expensive book anymore. There are also endless repair tutorials on youtube. Derailleur adjustment is explained well at Parks Tool site, along with many other places. Google is your friend. Sounds like you need a very minor barrel adjustment on that derailleur.
