Starship Combat: Stay on Target vs. Gain the Advantage

By dustin5, in Star Wars: Edge of the Empire Beginner Game

Okay, I have finally run the box set adventure "Escape from Mos Shoota" (which was fun) and I like the system so far. The only trouble I had with it was starship combat.

And now that I have read the full rulebook and about to run "The Long Arm of the Hutt" I have a questions about starship combat:
• In the pilot maneuver "stay on target," does the pilot and crew upgrade ALL of their ability dice for their rolls that follow that maneuver or just ONE ability die?
• Is the fact that the ship performing "stay on target" also gives an upgrade to any other ships targeting the maneuvering ship the reason why the pilot does not have to make a roll for this maneuver (like for "gain the advantage")?
• Can a pilot perform "Stay on Target" and "gain the advantage" on their same turn?
Like I said, I like the system so far, but the starship & vehicle rules are so far the only confusing thing and I think that is mainly because they did not give examples of the rules in play.
Thanks!
