"living in the fast lane" means to live life very fast. to be always busy, always doing things and to not care about concequences and to be a bit risky usually.

"to fast track something" means to accelerate a process or make it go quicker
so if you are applying for a job and you want to "fast track" the application then that means you want to make it happen sooner.
