I dont know if this has already been mentioned but, sets of pre-arranged sliders so it wont be such a pain changing them. For example: Sliders that will make the game more realistic and result in a low scoring game, sliders that will increase your shooting percentages and the amount of points scored, and of course the default sliders.
Also, I've never played Live 08 so i don't know if this is still a problem but, an increase in the amount of fouls called. I've set my foul sliders to 100 and yet I still get collisions in the air without a foul being called.
