Here are some answers:
1. No...its not any different. Although the dealer may not have many slots left..so they may not be as incentivized to deal...they still will.
2. You should shoot for whatever you want to. Read the bmw 535 forums over at bimmerfest, and see what they are paying. But DEFINATELY find out what INVOICE is on the car and options you want, and start there.
3. Yes its reasonable to get those dropped.
4. I will be doing ED next time I purchase a BMW. You can read alot more about it at the wiki....but you can get HUGE discounts in that program..if you use the right bmw dealer that understands ED. Otherwise you can use the buy who runs the site edbmw.com Here is the wiki:

5. Bimmerfest is another good one.
