Help with Templates Please

Hello all, I need some advice on Templates. I am currently using the solar flare template and I have been having some trouble the way some pages show up. Also i would like to change the layout. I have searched for other templates but can't find what I am looking for. What i would like to do is the following:
1. Remove the New Flash and have my banner go across the whole page.
2. Add my google ad's directly under the banner and go across the entire page
3. Add 2 or 4 advertisement spaces under the google ads that also go across the entire page
4. And to do this, i would have to push my main menu down further along with latest news and popular items.
5. Get rid of the powered by mambo.

Here is my web link so anyone can understand what i am talking about:
www.tampasportbikes.com

Also my reason for doing this is b/c on certain pages pictures don't fit and the page gets pushed down, as well as my new SMF forum it does the same thing. The Ad under the banner and all content below that gets pushed down the page.

Any help would be greatly appreciated.
