Hi, gengh1s! Welcome to LinuxForums!
Using SAMBA, you will be able to see and ACCESS files from Windows machines.
Not sure about Photoshop, I don't use it personally. But I've heard good things about getting Battlefield to run on Linux boxes. Wine, Cedega and all the rest do have limitations, so I would advise keeping a Windows partition active until you get used to the Linux way, and to make sure you can run Windows apps that may not have a Linux equivalent.
As far as some info to start with, you can try the link in my signature. It may start you off in the right direction.
Visit often, and enjoy your stay!!!
