NCAA Football question (PS3)

I am thinking about getting NCAA football on PS3, gotta play as my beloved Horned Frogs.

Anyway is there a way to get the roster names on it from online or putting the file on the memory card?

I get my sliders from here. The Heisman sliders were great for me. It took me about 6 years to win the Title with Houston. http://www.sportsgamer.com/forums/forum686/

As Far as rosters, FK are supposedly the best. I think it is recommended that you buy the disk as it is easier. I don't really know tho', as I never do it. http://www.fkrosters.com/
