I want to add a tidbit to Tester101's answer. One very important difference is the grounding wire (green or bare copper) should never have current during normal operation, while the neutral (aka grounded, typically white) wire always carries current in a 120 system (this is the return path for the hot). This was stated in Tester101's answer, but it is ...

"I think we're gonna need a bigger box!" If it's not too late, change out the 4x4 box that will have the GFCI receps for a 4-11/16" box, with appropriate domed cover or 2-gang mud ring. Two GFCIs in a 4x4 will be a very tight fit with almost zero side room... but 4-11/16" are a comfortable fit. No, we're definitely gonna need a bigger ...

Note that you may not have realized but the safety ground wire in 12-2 Romex is sometimes a smaller AWG than 12. In situations where this is allowed by code it may be a 14AWG bare copper wire. Knowing this you can re-check the wire nut capacity for more conductors. If I was addressing this I would bundle the three safety grounds from Circuit A together with ...

Yes you can use a 2p breaker for individual circuits (the neutrals must remain separate), and you can daisy chain wire connectors in order to connect all grounds.
