I'll address a few of your questions.
With life insurance the commission rate varies greatly, from company to company, and product to product. Term 20 (twenty years) a decent commission is 80% of the first years premium, you may get up to 100+% with some companies. Renewals don't exist much anymore on term life, some companies still pay it, like Illinois Mutual at 5%. Whole life commissions are all over the board also, but they pay renewals, maybe 15% years 2-3, 7.5% years 4-6, and 5% thereafter.
It's a great business, but it's not get rich quick. I've heard it said many times that it's get rich slow.
I'd suggest getting your license while you're still selling cars. Get appointed to sell life insurance, start there, get your feet wet, and see if you like it.
Who to get licensed with? Illinois Mutual is in your back yard.
