Multiple recepticles in a circuit which covers multiple rooms, all controlled by a single GFCI receptacle
You should never have more than one GFCI device on a single circuit, as they tend to interfere with each other and cause each other to trip.

I may be wrong, but I also don't think it's technically permitted to have outside circuits on the same line as inside (garage) circuits.

Regardless, your best option - especially since you're probably operating heavy duty equipment in the garage - is to put the garage on its own circuit.
