I just bought a Venom pro and want to charge my 2500mah Stickman with it. What volts and amps do i discharge and charge at?

That is assembled using AAs if I'm not mistaken. I would not charge at more than 1amp and if it gets too hot at 1amp, I'd reduce that to 0.5amps. Discharge at 1amp.

I ask cuz i got this new charger and not familier with all the settings

Charge as NiMh, 5 cells, 1.0amps with peak setting of 5mv/c. Stay with it during charge and monitor how hot its getting. Pack will get hot, but shouldn't get more than 120F. If it gets hotter, stop charge, let it cool and re-try using a little higher peak setting (7mv/c).
