Internet Explorer Problems

I am using the Cutline 2.2 theme with modified code. My blog looks great/perfect in Firefox and Safari, but I am having the worst time making it look good in Internet Explorer. The header navigation is displaying wrong and the images in the posts show up about 1/4 of the way down the page. I tried copying my style.css and making ie6.css, ie7.css, and style-ie.css and put them in the same folder and put a hack in the code for IE to use those stylesheets, it didn’t do anything. I also tried just taking out the IE fixes entirely but that still didn’t work. I ran the code through a validator and tried fixing the errors, but I am not an expert at this at all and am having trouble fixing all the errors, I would like to just make it work in IE and move on. I am working on a deadline and could really use some help.

Do you need my code or can you just view the source from the browser.

Any help would be greatly, greatly appreciated, I have been scouring these forums looking for answers and the above was the best I found, but I’m still not getting it right.

Thank you in advance.
