I've read that my camera doesn't support wireless commander flash. I've also read that hand-holding your flash (and/or having multiple flash units wirelessly away from the camera body) is quite useful.

I'm curious about what the best flash option for such a camera body would be?

Also, for built-in flash diffusion, could I simply use a shopping bag or something? (On-the-go diffusor that can be pocketed and used on my cheap-o flash unit built into the camera)

Yongnuo YN-568EX is the best value for money ttl flash, performs brilliantly
I have a few YONGNUO flash units and they all perform flawlessly

defused off-camera flash is the best, but not always practical
although I have shot entire weddings that way, on camera is so much easier
basically if you are shooting on-camera you will want to bounce the light, either off the ceiling, wall or a large reflector
a plastic bag isn't going to help you much, neither will the bought diffusers for a pop-up flash
once u get a flash this will help a bit:

but as said bouncing the light works better
