Supplier names for parts on a 71 Eldie convertible restoration

I just got my project car.  My first, and it will need Lots. Of. Work.  It's a 1971 Eldorado convertible.  I don't know what all it needs mechanically yet, but I do know the interior will be a total overhaul.  Dash, door panels, window switches & motors, etc.  As far as the top, carpet and seats, I've already got contacts for them. 
 
Also, which repair manual is best?  I'll look for an original GM shop manual for this car, but may have to look at a Chilton or Haynes.

Check e-bay for fsm.
