Any input is appreciated.

I actually changed my previous plans and changed to a 11.1V lipo. I find that with the rate of fire that I wanted, it was more efficient to run a 11.1V.
I'm afraid I won't be much help here because I am running the battery outside of the gun, inside of a battery pouch, so I'm not restricted by the size.
If you're running 7.4V, that battery spec you posted should be fine for stock.
Voltage (7.4V vs 11.1V) - This depends on your rate of fire. If you plan to upgrade the rate of fire, the drum, and internals like I did, then I would suggest 11.1V. A 7.4V is good enough for a stock gun with normal rate of fire. Actually, most support players would might prefer a more moderate rate of fire to conserve ammo.
mAh rating - The larger this value is, the longer you can stay on the trigger and on the field. This is important as a support player, since your task is to suppress and provide sustained fire. You don't want to run your lipo completely dry. This is dangerous and bad for the lipo's life. With a 2000 mAh, I estimate you should be able to run it for about 5000 rounds on average before you should change it.
C rating - You need a sufficient C rating to give the gun the power it needs. mAh x C equals the maximum Amps. So in your example, 2000 x 15 = 30 Amps maximum. In this example, your stock gun will be absolutely fine. The higher this limit, the easier it is for your battery. You don't want to work your battery to the limit all the time. The more headroom, the better.
