Integrate Wordpress / vBulletin

- I would like to integrate vBulletin with either Wordpress 3.0.5 or 3.1 - I would also like to have facebook login, facebook "like", and twitter "re-post" located throughout my site. To encourage the Members to get my sites name, posts and threads posted out on those social sites more frequently. - I would like to keep my style so I would need the conversion of my current vBulletin theme to a Wordpress theme. - ALSO Need the integration of a ranking system for up to 200 products on 1 page: I will also need a ranking system / voting system for a competition that will start on March 1st. I need something integrated into Wordpress or vBulletin that will allow ONLY my Members to vote/rank products. Listed on 1 page.
