4. Most dealerships now have an "internet salesman" - you go through him rather than the guy who runs to meet you when you get to the lot. Ask for one by that name.

I would move your step 4 to step 2. There is no reason to walk into a dealership and let some random saleman standing at the door for the next customer take you on a test drive. You potentially do open a situation where salesmen are fighting over the commission if you buy a car there. Just email the nearby dealer internet sales group and tell them you want a test drive. Almost every time a time has been arranged for me and the car is waiting for when I arrive. It cuts down a lot on the time involved there.
