1: scrollbar styles affect a few non-IE browsers too. I never use IE for
surfing, but I see your colored scrollbars in my non-IE browser because
I've allowed it to act on those styles.
2: that proprietary stuff doesn't validate is as expected, and does not
invalidate the regular styles. So if you're sure the styles are ok and
work as intended, then there no real harm done.
If "total validity" matters and you want to keep the proprietary styles,
Conditionally Commented stylesheets for IE only stuff is an option.
This approach doesn't make the styles valid, but for most "hidden" is
good enough. Besides: the stuff will not show up in non-IE browsers when
CCs are used, which I personally think is more important.

Background-color is layered behind background-image, so normally setting
a background-color as fallback shouldn't be a problem.
The shape / transparency of the background-images you're using may force
you to declare an actual background-color further back, and since the
validator can't see your visual design it can't clear you on that point
- hence the warning.

Warnings should not be ignored, as what they're usually pointing at is
something that may conditionally fail at the visitors' end. The
validator can't check all "what happens if", so it simply tells _you_ to
perform such checking. Only when you have manually checked and are sure
failures can not occur, can you safely ignore these warnings.
