Vista - Vista & Explorer

Hi,
I know internet explorer is more and more becoming an integrated part of windows but there are a few silly things that annoy me a bit that I thought I would ask about to see if I could change them.

First is the drop down menu in the adress bar. Lately I have noticed that web adresses are mixed up with computer related...uhh stuff. So in other words when I am browsing on the internet and I click the drop down menu, I am seeing links to My Computer and My Documents mixed up with web adresses.... if there anyway to stop that from happening?

Secondly is the theme, I am using a High Contast Black theme, where the screen is mostly bakc and the text is white. This theme (unlike in XP) carries over into explorer...which I didn't really mind, until I realised that it was blacking out alot of pictures and visuals. So my next question is, is there anyway to stop the theme I choose from influencing Explorer's webpage display.

Any suggestions would be greatly appreciated
thx
