1/ You've got to set up the order for the flight group to "hyper to region #", Region 2 (can be done easily with AlliED). Set the first waypoint for this order near the hyperbuoy, otherwise the crafts wil enter hyperspace immediately.
2/ You've got these options available in AlliED. NB: when you launch missions from the flight simulator, it does propose all Rebel ships, whatever you have set up (so I think).
