As everyone else said, it would help to know how handy you are. I did everything myself and saved a ton, but you may not have that luxury. If you can't wire for example that would affect what people suggest to you. My basement was pretty cheap, but I splurged on certain things like thin brick in one room and a nice theater. I did everything myself and didn't do the full sound deadening package. Keep in mind that if you ever go to resell, being up to code and having it look nice is important

Definately go with the permit. It's cheap and forces you to have your work checked. The blueprints were the worst part for me as I hadn't done anything like that before. Most of the rules in that permit notice are code things, so you would be doing them anyway. Your property taxes may go up, but that's because your home value also just went up.

I installed dmx dimpled underlayment. Cheaper than dricore, I highly recommend it. You can get it from home depot. My only regret is not installing self leveling compound firsr because I can tell there was high and low spots when i walk on my finished floor
