You should have mentioned the time, date and location in your first mail.
No special software that I know of, just QuickSat or a graphic prediction
program like SkyMap, which can predict only objects in a given time and 
coordinates "box" (seeing the tracks and times on the screen helps)

Yes, if they where bright enough to see without binoculars even 
inaccurate observations can be identified, and lots of members usually
respond when "UnIds" are posted.
