Text size issues and misc. space questions.

I've been troubleshooting some issues I have with my store. Unfortunately, I've gotten confused and would like someone else to look over this.

FIREFOX


1. In both Firefox/IE there is a ~ 40pixel white space between my Flash navigation bar and the body beginning (see either pic below.)

2. There is a problem when viewing the Header & Footer in Firefox. It seems like its only my pc. If you use Firefox can you please verify that this is only on my pc. Compare with the FAQ page.

3. In IE the home page (and maybe a few others) don't center the whole table. If you navigate to a product page it will be centered.

4. The main page body/category text seems larger in Firefox. Compare with the FAQ page. That illustrates the proper text sizes.


Any help resolving these issues are greatly appreciated.
