Need a little css help with directory...just floating and aligning

Got the sidebar in but can't get my css to cooperate. Care to take a peek? Here's a screenshot of what I am trying to achieve. Sorry again for the subject rather racy subject matter. Client is very nice.

Just can't get them side by side, and the boxes aligned all pretty.

I'm in the home stretch on this site, and it's been the most complicated thing I've done. Thantks for all the help.

Thanks if you can show me. I'll grant access for the site.
