The torque curve is moderatly flat, but where it crosses the HP numbers, the HP has already peaked.

Is it just me, or is something wrong here?

If I understand correctly you are saying that peak HP happens at a lower RPM than the peak Torque?
If so, something is wrong with the plot chart or your interpretation of it, or my interpretation of your statement.

IF Torque increases as RPM increases than HP will also increase. HP will continue to rise as RPMS rise as long at torque is constant or begins to fall quicker than RPMS increase.

As far as which is prefered Torque or HP....the more gears you have to choose from and the more constant the speed of the track is, the less important torque is.
