Aliens are common on Absolom Station.
From the Pact Worlds book, p40-41:
Absalom Station is a melting pot. Though many see the station
as the hereditary home of all Golarion’s races, particularly of
humanity, today its corridors are choked with natives of many
planets, and its status as the primary waypoint in and out of

You miss Ace Pilot character theme.
It states that Ace Pilot gets pilot as his class skill, but if it's a class skill for 1st level - Ace Pilot gets +1 to their piloting.
So, piloting should be:
4 dex + 3 class skill +1 Ace Pilot +1 Rank + 1 Operative Edge = 10, just as in charsheet.
Specializations says that you gain Skill focus feat and one free rank at ...
