...not familiar with this "fuel map" option; can you help me out and describe in greater detail? Thanks again.
I'm even newer, first season with a license and my own bike

Also I'm just a software engineer, not a mechanical engineer, but I'll give it a go.
The amount of fuel injected to the mix that goes into the combustion chamber is controlled by the ECU based on one of two factors:
In closed loop mode it adjusts the mix based on info from the O2 sensor. When this mode activates depends on Ducati's programming, usually lower RPM / throttle position and probably not if the bike is cold as the O2 sensor is calibrated for operating temperature. This is likely the mode you are in when stopped in traffic.
In open loop mode the amount of fuel injected is based on a map, which is just a lookup table saying how much fuel to add at any given RPM count.
The map can be changed by your dealer, if you buy the not road legal Termignoni race exhaust, or by having your ECU reflashed by Rexxer, buying one of Rexxer's modules to do it yourself, or by using a piggyback unit like a power commander to trick the system. Closed loop mode can also be disabled.
In order to satisfy emissions regulations the bike runs most of the time with what some may consider to be a 'lean' mix (not enough fuel) and since fuel in the combustion chamber has a cooling effect this means there is scope to get the bike running a little cooler. Changing the fuel map can also make the bike a little smoother in response to throttle input as, if I understand it correctly, a slightly richer mix is more forgiving of any sub optimal combustion conditions that may arise. It also makes the engine sound a bit richer, which is nice, and I suspect running cooler reduces stress on the motor a little.
I disagree with Black Dog's assessment of it all being a waste of time and money and I will probably do it at some point, but I would not expect any drastic changes. It's the same motor, after all, and still air cooled at the end of the day.
I also feel it on legs, not balls, and I always wear riding pants.
