That isn't going to be easy. First you'll have to take stuff out of the div of class "content_container" and div of class "sidebar_container" (search in templates to find them). Maybe even take them out of the div of class "content" also. (Not tested, I'm just guessing, you can try that on a test style.) Or maybe just delete those classes from the css (again, searching in templates should give you the css template).

As for the tabs, just remove this line from the MEMBERINFO template and I think it will get rid of them:

<script type="text/javascript" src="clientscript/vbulletin_tabctrl.js?v=$vboptions[simpleversion]"></script>

Not tested.... I don't think it will break other things, but you'll have to see.
