There's a picture of the guys pump system carbonator here http://www.angelfire.com/cantina/carbonation/PumpSystem.htm

Myself - I wouldn't bother. I've read a lot about this kind of thing for corney kegs, but find for myself that just applying pressure and shaking them does the job just fine. Other times, I just turn on the high pressure every time I wander by the keg for a few seconds, until I get the pressure I want. You could do either with your bottles and It will work fine too. The more open space at the top of the bottle, the less times you will need to repeat the CO2 addition for the desired result.

Q1: How do you know when you're "almost out" of liquid in a C02 tank???
