1) Yes. But it is not easy (yet). The way I did it for nanosail-D was to copy their TLE's into a file. I put that file into a directory by itself and had gpredict reload elements from file using that directory.

2) Yes. But not in length of hours. It is instead specified in # of orbits. The map view tab under modules in the edit>Preferences menu is one way of setting this.

3)In software, no not at this time.
