All these things that I have done

Seems fine; however, as to the text size, the problem would appear to be that the rext size your style sheet uses is not affected by the text-sizing options in IE, although Mozilla's text-zoom works fine. So, your style was showing up as teeny-tiny in IE. It seems to be OK in Mozilla, now, though.

Much better, and doesn't have the weird formatting glitches I experienced previously.

Instantaneous! Still got the IE vs. CSS box problem though...?!! Doesn't inline styles cause a problem if you want update the stylesheets? No single point of contact and all that...?
