Failed state emissions
Just failed state of NJ emissions. Reading was "not ready". 2010 XKR has been in the garage for a few months. Do I just need to drive it awhile to reset and then bring it back for retesting? Also, don't know if this is related but had TSB J038 performed in Feb. 2015.

A 'not ready' means you need to drive the car, usually a few hundred miles under varied conditions (highway, street, idling) because the monitors were reset after the repair. It does not necessarily mean there is a problem.
Also, make sure you do not fill up until you reach below a quarter tank so the automatic tests will trigger properly.
BTW, most OBDII readers will report the state of readiness without going to the test station.

"WhiteXKR" is correct. You have emission readiness monitors in each late model cars that have to have completed their test cycles before displaying a "completed" result. Without those the smog test stations are not allowed to perform their tests. In some states you can get by with one of the 8 monitors not being "complete". I had gone through the process a number of times and in the most extreme case it took 1150 miles of driving to produce a complete set of monitors. Lots of wasted gas and hours of driving.
Like posted above, during the drive do not fill up completely as most cars require a gas tank to be between 1/4 and 3/4 full in order to perform one of the 8 tests, I believe it is the Evaporative System checks.
I do have an OBDII scanner that is working with my Android smart phone that shows the status of those 8 monitors. That truly helps, instead of making repeated trips to the smog station just to find out that your monitors are not ready.
Terrible system...!
