Wordpress Help

I have an RSS feed adding articles to my Wordpress. The feeds are according to keywords, but all of the feeds are going under my default category. Is there a script or plugin that I could use to make the articles fall under the category for there keywords? Thanking you in advance for your assistance.

I don't mean to steal the thread but I could use some advice on putting RSS feeds onto pages other than the front page.

Crude example would be something like

eBay Trucks
Chevy
Ford
Etc.

Thanks,

CB
