First a few comments.
An E92 is a good car... a good street car. Can it be made to race? Sure, but understand that if your goal is to reach the professional ranks, the series where you will be running will need annual budgets well in excess of a few hundred thousand dollars every year.
Second, you say you have talent? What are are you basing this on? It's fairly common to hear a novice driver say how talented they are before they've turned a single lap... and if you haven't turned a single lap (which seems likely since you are here asking), you really have no idea whatsoever how talented you are. Driving since you were 5 is a plus, but unless you've been racing, you really don't have any related experience (racing and driving around on the street is not really that similar).
So, the first thing you might want to do is look at the tracks in your area where you would be likely to run on a regular basis (Las Vegas, Spring Mountain, Reno-Fernley) and see what SCCA and NASA classes are out there and offer a chance for regular racing. Then figure out what your actual budget is to spend each year - this number is much more important than your vehicle cost! Then when you've found the class you'll run, start looking for the car (ideally get one that someone else has already spent the time on, but getting one and building out can be good too, though much more costly... you will spend MUCH more in prepping the car than in the car itself). Get your safety equipment, tow vehcile, tools, etc... then you are ready to start.
While the Russell school in Sonoma is a solid choice, or Barber or offerings you'll find at Spring Valley or Las Vegas, such schools come with two major caveats 1) they probably are not running the car or even the same style of car that you will be competing in, 2) they are not really aimed at complete novices (you can take them, but you'll get much more out of them if you actually have some real driving experience first). On the second part, look for HPDE and Open Track events... even autocrosses and such in the area and get out and start driving. Take instruction whenever and wherever offered and start the long climb of learning how to get the most out of the car.
Then, decide if you're better off with one of the above schools, or taking your own car to a NASA or SCCA school. The former are much more costly as they will provide all equipment, but all proivde great instruction and will end with you getting your provisional license. From there, you'll get your regular license after competing one or two events as long as you avoid incidents or give cause of concern to the race stewards.
Once started, seek out a good coach that you can work with at Open Track and other test days to help keep you improving, and to help on the setup issues that will be very alien to you for quite a while. If you have a natural talent, you'll eventually start to have success as you develop as a driver (even with talent and coaching and some luck, this is probably still a few years, likely many more than that). From there you look to move up to higher series and hope that you might attract professional attention.
One last comment - if your goal is professional, you will be much better served as a driver starting in a slower car that will require you to use all of it's momentum to turn a good time, and move up to faster cars only once your driving basics are in place (Formula Vee, SRF, Spec Miata, or even some of the karting options make the most sense for starting out irregardless of how much you can spend).
