Since the OP came here looking for advice and has a short time line, I must assume that the OP has some GPS knowledge since they are planning to do a portion of the TAT for an Iron Butt and would have needed to create the Tracks necessary for navigation at a minimum.
If they have no knowledge of Garmin GPS's or BaseCamp then they have no business taking on the TAT with any GPS and should stick with the Rollcharts and paper maps they purchased from Jim.
