Welcome! Glad to have you on board, good to hear about the DF bit in particular
Old school textures are hanging out here:
https://github.com/begla/Blockmania/tre ... a/textures - they're mostly from the texture pack we're using, and I expect we'll slowly replace them piecemeal with our own contributions
I'm working on a new school texture approach where individual blocks will be split out and dynamically merged into a single texture image on world creation - under that system the block textures end up stored under here (but it is still very early in development for that feature):

Are you interested in any particular artistic area? Blocks, structures, creatures, GUI, etc?
If you like, try going through the first few steps here to get setup for local dev (if you haven't already):
http://wiki.movingblocks.net/Main/DevSetup - I'm happy to get any feedback to make the instructions better, I'm sure they're fairly raw for non-Git experts (like myself, heh). Even if you're not heavily into code that would be the easiest way to contribute (and test!) new art
