The lounge is at the elevators in the middle. Go up one, look around. I think the station's jukebox is there too. I'd love access just to change the damn song sometimes.
In space combat you have armor and shields. Shields regenerate but only when you're not firing lasers(missiles firing is fine). Armor doesn't. You have a ship, you should try it. Talk to the terminal by your galaxy map if you haven't yet. Fondor Escort is the first one, fairly easy to do, especially after you do it a few times.
