Boot from the snow leopard installer DVD, then when it asks to choose a disk, choose the external drive. Wait for the install to finish and restart the mac then install diskwarrior.
The installer will set the external drive as the default startup drive, so open system preferences > startup disk > reselect your internal drive and click restart. You just hold alt at startup to choose either the external or internal disk.
