SET Tube Question

I am very new to the tube world and high end audio so I hope I don't get flamed. I have just acquired my first couple pieces of gear a pair of Belle Klipsch speakers, a custom made isoberic sub made to match the Belle's, and an EAD MK III cd player. I have been doing alot of research and reading and I would like to try a SET amp first but there are so many different types of tubes and tube gear it gets a little overwhelming. Is there a tube gear guide for dummies out there or other recommended reading? Any advice or recommended tube gear to compliment the Belle's would be appreciated.
Thanks
