Hi Joshua,
Written in haste...
Firstly if you are going to add unique content to each of the pages that makes them each a best in class page for the terms that you are targetting then the dup issue will be resolved (assuming that you optomise each of the pages correctly).
Content about the individual woods, doesn't sound good enough to answer the queastions a searcher might have if they were searching for "Sapele Countertops".
In terms of Jquery, it sounds like you need to figure out what you are trying to achive in the first instance.
let me know the following and I will try to help further:
Have you any evidence that these terms are searched for?
Do you have any idea of keyword difficulty http://pro.seomoz.org/tools/keyword-difficulty for these terms?
Depending on what your trying to achieve you have loads of options.
Hope this helps.
Justin
