You guys need to look for the (pick your faction) Pilot Trainer. He'll appear on your "m" map overlay in cities that have them. I know Coronet has a neutral trainer. Do the missions, collect the xp, sometimes you get rewarded with a skill you don't have to buy.
Oct: On the ground, the only thing you can do to improve space flight performance is buy better stuff for your spaceship. Skill restrictions make it not all that important. You'll find it's a very long grind to Master Pilot. The fastest & most effective way to do it is to join a guild, find somebody with a YT-1300 freighter (mullenium falcon), and fly with them as a turret. You'll blast stuff way beyond your level and make xp pretty fast.
