If I understand it correctly, you'll first get a 'provisional' (or temporary) green card, which will expiry after 2 years. On expiry you will have to re-apply in order to get the permanent one. However during the time you have applied (petitioned) for the initial green card, but have not been granted one yet, I would expect you do still have a legal right to be in the US due to being married to a US citizen.
Note however that no green card is permanent - the US has to right to revoke it in case you live outside of the US long enough (don't know the exact rules about it, or even if there are hard rules).
Anyway, I agree it will probably be fun to go through the process
