Are you making a whole Piper-verse setting, or just using some of his worlds as inspiration for an area of your regular Traveller setting?
As I'm sure you know very well, Piper's space tech is significantly different from Traveller jump and maneuver drives.
Piper's FTL drive is described as hyperdrive, but seems to share some characteristics of Jump drive. Although it doesn't seem limited in distance as Traveller Jump drive, it does seem that once you set your hyperdrive destination and push the Go button, you are essentially fixed on that course until you exit at your destination, which is somewhat like Jump, rather than like some other SF hyperdrives which allow the ships to change course while cruising at FTL speeds.
The implication that I gather from descriptions of hyperspace travel is that jumps are set from where you are to the edge of the system where you want to go, then after observation of current positions of planetary bodies, microjumps get you closer to your destination, then Abbott lift-and-drive takes you into atmosphere, then contragravity is used for landing (I think the most complete description is in Space Viking, when Nemesis first enters Tanith system; this includes the astrogator discussing his planned microjump and the possibility of bounce-back).
There is also some discussion of the differences of contragravity versus Abbott drive in Cosmic Computer, when Conn builds the ship to investigate the abandoned industrial planet further out in the same system as Poictesme.
EDIT: I forgot to mention, with the ready availability of mass conversion units, there are no fuel issues. I once did some math on the energy production from total conversion, E=MC2, and it was amazing. Unless you posited extremely low efficiency of conversion (and then where does the excess go, waste heat?), the result is that you might as well not bother tracking energy usage at all.
