i can't tell you if it's a good idea or not, but i can answer your other questions.
1. feeds for each category is possible by default. http://www.your.domain/xmlsrv/rss2.php?cat=1 or 2 or 3, ...
2. do you need the category in the url? because a url like http://www.yor.domain/index/2005/01/27/title is already possible
