Hi Dave,
Just a quick suggestion...

Try using PCB's feature for importing schematics instead of using
Gsch2pcb... you'd just start a new layout with pcb and then select
'Import Schematics' from File menu. Much of the craziness of gsch2pcb is
sidestepped here.
If you have multiple schematic pages, select them all when importing,
the PCB file will then remember these files as the source for the info
about this design. Save your new PCB layout and untangle your hopefully
visible rats nest!
HTH,
Ed
