The ones you mentioned specifically, AoE and DPS (not DSP), mean Area of Effect and Damage Per Second. AoE in this game is largely communicated with red shapes on the ground; it's just the area where, if you stand in it, you will get hit by an ability.

DPS is what it sounds like; how much Damage someone is doing every second.

Here's a link I just quickly found that may help out:
