vB4 Top logo centering and ad placement question

I have used Lynne's CSS edit as described here to center the logo for my site. I had a small (125 X 125) ad just to the right of the logo when it was justified to the left. Now, that ad has been pushed down to another line (as Lynne indicated that it would move things around) and doesn't look like I need it to.

Here's the question; I would like to have a small ad to the left and right of my logo and have my logo centered. I am in over my head as far at the HTML and template edits so any help offered is appreciated.

Thank you.
