agreed with zk0, wayyy too many links!! lol
try shortening it by only having the subheadings of the "browse by..."'s, rather than listing all the permutations. upon clicking on one of the "browse by"'s they can be redirected to a page with all those links.
also, if depending on your coding expertise, you might want to try making a tree branching thing for the browse by's, and be able to keep them on the main page too.
forecasting that you do take out the huge lists of links in the middle, the sidebar is going to look quite long. so you should then move some of that sidebar content to a new sidebar (on the right side). hopefully this isnt a fixed static template and you can do that somehow cleanly.
good luck!!
