Thank you all for the helpful response,
Currently, the only image-work we need are logos and such. Also, unit icons and player portraits would be useful later on. I'm not sure how much we can mod the SoaSE UI Interface, but depending on that, we may introduce a new UI and will need artwork for that as well.
As far as models and textures go, the people working on them right now are having problems re-texturing them to SoaSE format, so if anyone knows anything about this it would be helpful. We'd like as many models and textures for ships of both the FreeSpace 1 and FreeSpace 2 eras as we can get.
Also, we're here to recruit. Anyone with modding knowledge of SoaSE and with general knowledge of the FreeSpace universe are very much welcome to join the team.
