| Are these identical in Common Lisp?

no.  '(a b c) is identical to (quote (a b c)), which evaluates to (a b c),
a list of the three symbols a, b, and c.  (list a b c) evaluates to a list
of the values of the symbols a, b, and c, and thus depends on the value of
a, b, and c, at the time of the call.

e.g., 

    (let ((a 1)
	  (b 2)
	  (c 3))
      (print '(a b c))
      (print (list a b c))
      (values))

prints

    (A B C) 
    (1 2 3) 

I didn't understand your second question.
