If by luck you happen to find your way in situation #3 where you are being groomed by a team to run their car in an upcoming season, that would be the best way to go by far. Unfortunately, that's a long shot. And its not that im saying one you may or may not be a great driver, but the fact is anymore that top of the line teams are few and far between. These established teams generally have their pick of the top drivers and want results immdietly.
The second option you listed would be the most realistic and the best situation, assuming you can find a team to work for that pays a decent wage. Being at the races and making connections with people is paramount when it comes to trying to male a career driving for a living. In this sport rides are few and far between. In alot of cases teams that can don't always hire driver exclusively on their accomplishments. Teams often hire drivers due to the fact that they know who you are and like you. Also, being around the races working for a establashed teams can lead to sponsorships or discounts.
If you're wanting to make a living as a racecar driver you have to be a familiar face in the racing community.
