NASA doesn't normally have its own pilots - they're military pilots (usually former test pilots) who are assigned to NASA operations. It's common for NASA to use personnel from other agencies like DoD - I myself was a DoD Inspector assigned to NASA operations for 9 years.
When you see chase planes escorting a Shuttle during landing or patrolling an area during launch, they're from the local military bases in the area (Cape Canaveral Air Station next to KSC, Edwards AFB, etc.). NASA does use helo and camera jet pilots for local security, but they don't have that many.
For the Astronaut program, being a Test Pilot is the only way to go, and even then you're not a NASA employee - you're still a DoD employee assigned to NASA.

Yes, the joystick was invented for NASA. It was originally used in aircraft for pilot control, and later adapted for use in spacecraft to control movements in 3D space. NASA continues to use joysticks in various control systems for their spacecraft and robotics.
