I miss being a know it all :P
Basically, to get strength up, you do Strong grapple moves. (RB + Right stick up or down) for the hold, and then the grapple.
For speed, just do loads of high flying moves off the turnbuckles, etc, until you learn other moves, live diving out of ring attacks.
Durability is basically sustaining damage, and not losing. Submission is performing submissions, and finding your way out of them, raise your charisma by taunting, and hardcore by using weaponjs (duh).
Buuut, you all knew that.
