Newbie to Vintage TV -- Got my first one!

Hey everyone! I just picked up what I beleive to be a 1958 RCA 21D8525. The cabinet is in great shape except for the plastic emblems on the front. The set looks 100% complete...

I'm not new to vintage electronics since I have been involved with restoring old pinball machines...but tv tubes and stuff are new to me. Anyway...I know from working with pinballs that I should not simply power this thing on to see if it works...so I have a few questions:

Does anyone have a copy or know of a good site to get schematics and owners/repair manual?

Anyone want to help a nubie out with some good internet resources or names of books I should ask for at my library?

Is there a faq with general startup procedures before I start trying to get it working, or just a general TV restoration Faq?

Anyone have a clue what this might be worth if working?

Thanks, and sorry for asking so many questions in my first post!!!
