Hey,
I am fairly good at creating seamless textures, i am not familiar with the format they are supposed to be in,
but give me a texture, and i can make it to a SEAMLESS texture with ease.
also i am not that bad at creating textures from scratch in photoshop.
I have been itching to use my photoshop skills, i promise to impress...

I am also assuming there are other photoshop experts who can help with this task
Probably best place to get maximum returns is with the ground textures. Eloth has redone some of them, and I'm not sure which ones. Maybe send him a pm and figure out where you can start.
[EDIT] Here is a link with the updated landscape textures: https://docs.google.com/uc?id=0B_4xHMKqfAkdZXNtSENMS1VyVXM&e...
