Looking For Gallery Plugin

I’m an artist who uses WordPress 3.0.4 with the Headway theme. I am trying to build a gallery section; right now I’m using NextGen, because that is what my webmistress suggested. I don’t know how to make it do what I need. Maybe I’m using the wrong plugin.

I want to be able to list information about each piece of art work next to the thumbnail. For example, I’d like to include the title of the piece, the media, the price and whether or not it has been sold. A slideshow is nice, but not really important. I’d like it to automate the thumbnail process, of course, and perhaps do an automatic watermark.

Here is an example of the layout I’d like: http://saravanderkleed.com/

Any suggestions? Thanks!
