take a look at the /examples/extended/optical/LXe where you can find how we solved the problem of only drawing those trajectories which both hit the metal sphere inside the scintillator and a PMT. The example should also be a good source for other 'goodies' like UserTrackInformation etc.
The problem with track objects is that they are not around after the tracking is done. So, the TrackID doesn't allow you to fetch the G4Track object at a later stage.
