altering side bar

I’ve been wading through the message boards for a couple of days, and have found answers to all my questions, but 2.

1) I have set up 2 Links Categories, Blogroll and Onsite. I would like to separate them in the links section of the sidebar… Is this possible? and if so, where can I go for the information on that?

2) I imported all my entries from moveable type, and it worked like a charm… however the archives list is LONG. Is there a way to change it from monthly archive listings to annual? So there is just a link for 2001, 2002, 2003 etc…?

any help anyone can offer would be GREAT! Thanks
