I agree with taking it easy, and comfortable. My 1'st time driving a FED in 1963 [ before RED] I had some visual experiences. You see your brain is your computer, your eyes are lens, and your ears are microphones. So what happens is your brain is not used to [ programing] for taking in all that data so fast. Each pass you'll feel more comfortable as you brain gets reprogramed, plus the affects of adrinalin [sp?]
Some racers I know had fogging problems until they installed a helmet breath guard, from a motorcycle/ snowmobile shop. It keeps your hot breath off your shield. Check the M/C snow shop for anti fogging stuff. When I was driving at night I would put my goggles under my shirt before putting on my helmet so the goggles were the same temp as my face, ala no fogging. Of course that when open face helmets were legal.
The best would be to go to a Frank Hawly driving school, and they have you take it in steps, launch 1'st 2'nd 330', 3'rd 1/2 track, etc.
I always practiced each step of a run, sitting in the car, to program my actions/ reactions, so I did each step automatic. Don't worry about the blower visual issue, you'll drive it looking down the track just keeping the car in the center of the track. My worst visual was my dual engine BBC Top Gas Dragster, were I sat low enough behind the motors so my line of site was in the middle of the blowers.
A 6 foot tall person could stand at my front axle and I could not see any part of him. But then again nobody should be standing there before I make a pass.
I hope this all helps !
