What are you looking to do Cosmo? I play the PC version strictly for association mode (360 for online quick games). So the type of mods I use might interest you. I mainly look for stuff that updates the look of the game. Cyberfaces, courts, dornas, backboard ads, jerseys, and shoes.
First off, I downloaded this:

It unlocks a bunch of stuff from the settings files (all the classic teams, unis, Jordans, and other stuff).
Next is the special uniforms:

It adds textures for some unis unlocked in the first link.

Se7six's shot clock mods are top notch also. His mods are in this thread also.
That's the main ones I use to update the look of the game. People are still updating a lot of stuff. So a lot of stuff is still incomplete. Cyberfaces are a personal preference. These mods don't change gameplay. And this is just my opinion. You may try some of these mods and think they are terrible. Just remember to make back up copies of the files you change.
