Thats exactly right, lots of paperwork. They will really only talk to you if you go in to your venture with your own money. All types of incentives doo exist that can work in your favor, such as you will create jobs, hire disadvantaged workers, to name a few. However, no different from a bank, you will basically need a down payment, figure about 10% of what you want to borrow. All they really are is a conduit to the banks. Bigger banks are more anal. On the plus side SBA will put you through the grill, that should should only help you put many things into perspective when it comes to either starting or running your business, in terms of marketing plans, accounting etc. And when you have time to spare, thats when you get to actually run your business.
I would highly recommend you talk to them as the programs change all the time, go in there with some decent raw numbers in your mind as to how much of you own cash you have on hand and how much business you will get to generate. You can bet on spending money on an outside marketing anaylsis, and that is where your number need to be both honest, and look real good in terms of potential sales of your product, startup costs, etc.
