If you just want a little rigging on the side, really, you don't need to do much. Get the Command program at 6 with Optimization 1, and get the drones, and get Pilot Aircraft 1 (you can't default on that, but you don't need to be super amazing at Pilot).
The things you'll be missing compared to a more dedicated command rigger are no Gunnery, Commlink Optimization: Command, and Codeslinger: Control Device. You can't get either of the last two without giving up hacking abilities.
