A320 performance questions

[Minimums!]

hi guys, had some questions about the a320 performance:
1) at about 50 T GW what rate of climb do you get for a TOGA takeoff with flap 1?
2) what about after setting climb thrust and cleaning up (@ same weight)?
3) at around 180 knots with flap 1 and full speedbrake, what rate of descent should i be getting?

also, when in the sim is there a standard gross weight that you use?

thanks
