Hmm, the CSS validator over at [jigsaw.w3.org...] does indeed not see any problems with "font-family:Comic Sans MS,Comic Sans, cursive; "
But I would still write it as

font-family: "Comic Sans MS", "Comic Sans", cursive;

The other one that worried me is :

h1#logo, h2#logo {

While that's valid CSS, any single html document can only have at most *one* element with any given id.

It would help to specify what versions of IE are causing you grief. And describe the problem in a bit more detail ...
