Posts/Author/Background

Hi!

Where in Wordpress do I change number of posts to be displayed on the start page?

I have a widget, Latest comments, with the text "admin about" set to white, how do I change that to another color?

I would like to have a background image on the page, but when I set one the entire page goes transparent, including the center column, how do I avoid this?


Ok, I solved question no 1 and 3, but are still stuck on no 2, see my latest post ...
