New to custompress

Hi there! I'm a new wpmu customer and can't wait to implement all of these great plugins. The first that I need to work with is custompress. I understand the admin of Wordpress but need to figure this out.

I've written relational databases, which is what Custompress seems to be a front end for. Here's the project I'm trying to configure:

I am building a site for an art gallery. I figure I will have two main categories. First will be "artists"
Attributes to artist will be:
First name
Middle name
Last name
Born
Died
Picture
Biography
Links

I will also have a category called "pieces", which will contain at least the following:
Artist
Date
Price range
Description
Multiple images
Medium

I'd like to link from artist pages to piece pages and search by the criteria above.

I've read the data about taxonomies, but I'm still confused. Is there a better reference? Is there a specific forum group?

Thanks experts!
