It went WELL!!
I got there at 7am to setup, and my father-in-law, bro-in-law, and another friend showed up unannounced to help. It went fine, and I learned I need a real system to keep everything in order and speed things up.
We were set up by 8am, but the door to the adjacent building wasn't opened, so I couldn't plug in the Zojirushi hot water gizmos until almost 8:30. This sucked, because the other vendors all wanted coffee. Everything was warmed up at 9, just in time for the customers to start trickling in, and we were a bit slammed by the addition of the vendors who had been waiting.
After that, it was pretty steady, we served 85-90 cups of coffee in 5 hours, which is apparently pretty good for a slow holiday weekend, and our first farmers market ever. We also sold a few lbs of beans, but not nearly as much as I'd like.
I had wondered how the drip station would go over. Will people wait? Will I be able to cope with a crowd? Well, people are mesmerized by the process of making THEIR coffee, and it wasn't an issue at all. People have LOTS of questions about coffee and 'what's good'. I coped OK, but I need to change my layout a bit, and figure out a system when working with my wife.
The equipment recommended here performed flawlessly. The Zojirushi's are simply fantastic, a joy to use. The drip station from
http://www.espressoparts.com not only performed great, drew MANY comments, but proved to be worth every penny. I had ordered a Bunn G3 grinder, which didn't arrive in time, so I used my Mazzer SJ to grind a quarter lb at a time. Some might scoff at 'pre-ground' coffee, but it was roasted yesterday, and used within a half hour of roasting. Of course for espresso that would be unacceptable, but for drip I feel very comfortable with it.
Feedback was outstanding. Out of 85-90 people, I got 2-3 neutral responses, and 0 negative remarks. Lots of 'Oh WOW, that's AWESOME!'. It's really nice to be able to interact with the customers, as opposed the the last 3 years of internet only stuff.
Here's a few pics, though not great of the setup.

Thanks for the tips and recommendations in this thread. Invaluable! And yes, my shirt says 'Wake Up People!'.
