see what happens when you ditch the eval-after-load completely. i
suspect that installing tabbar-mode through elpa already activates it,
so what you're doing with the eval-after-load call is deactivating it

this is wrong. it should be:

note: the common way to write lisp is to not put the closing parens on a
separate line. just write:

(eval-after-load "color-theme"

looks much cleaner. (the parens are just there for the computer. as a
human, you should ignore them and look at the indentation.)

this is telling you that (color-theme-initialize) cannot be a function
(nor name one). which is correct, because it's a list. a list can only
be a function if its first element is the symbol `lambda'.

the reason why emacs thinks (color-theme-initialize) is a function is
because you've misplaced the paren with progn.

use the code snippet i gave above, it should (hopefully ;-) work.
