I am trying to accomplish two things with the Category tags.

First:

I'd like to have a sidebar with a list of the top level categories I have set up.

Example:
Web Design
Web Standards
Tools

I am lost in the MTCategories tags and can't figure out how to *ONLY* display the top level Categories.

Second:

I would like to have an informational strip across the top of an entry with the Top level Category - subcategory, subcategory2, subcategory3


Any help on figuring this out would be appreciated.

Thanks
