A program like Mike McCants' QuickSat addresses all of these issues. It generates for every pass a heuristic value that will help you spot an elset that should be freshened. It contains his photometric catalog which allows you to pick out only bright candidates, or at least know what you are up against if you choose to try for fainter objects, or newer objects with no observations. It can precisely calculate shadow ingress and egress, so you don't waste effort looking for objects 12 magnitudes fainter than the limit for your sky, something that radio-oriented programs with some visual features don't adequately do. QuickSat is available from the SeeSat-L archive, mentioned just below. The SeeSat-L mailing list serves visual satellite observers. You may send subject "subscribe" to firstname.lastname@example.org and also "help" and "archive help". Volume is only maybe 3 messages a day. You may wish to access the archive for the many discussions of visual observing. Recent messages have discussed the merits of the various lists and catalogs of bright objects, some of which are available from the archive. Elsets for bright objects are maintained in special files by the OIG BBS, Celestial BBS, and kilroy. The archive has a search facility called egrep. You can obtain information about the mailing list and much other material of interest to visual observers of Earth satellites, including Web access to recent traffic on the mailing list, by checking into the Web pages at: http://www.ipp-garching.mpg.de/~bdp/satintro.html and http://www.physics.ox.ac.uk/sat/satintro.html.
