 I would say that "timer" and "overlay" belong to
fsf-compat. 
Correct.

 Can't help you with these, though.  Can vc and vc-cc packages
co-exist
 peacefully?  
No.  Pick vc-cc *only* if you use ClearCase.  vc is synched with the
maintained version in FSF Emacs and is likelier to have fewer
problems.
