Are you a css guru, help!!

I’ve searched through this site but i was unable to find a fix to my problem.

I’m having problems with rss dead images and sidebar shooting out of its spot (internet explorer). The sidebar, and borders seem to be out of place.

Here are some quick details of my site (this is a large online gallery that i was trying to spice up with a nice interface… such as wordpress:)

https://www.poundit.ca (work safe.. i promise)
Wordpress 2.0
Scattered theme

Maybe someone has a few suggestions or ideas of things to try. I found it really strange https://www.poundit.ca/?cat=1 displays the exact samee page perfectly, confusing.

HELP
