Yes, you are correct not to parallel the secondaries. The resulting capacitance will cause significant high frequncy roll-off. Only the primaries should be manipulated for changes in gain/impedance.
I'm afraid you must use two transformers for stereo. No good way around that.
Perfboard with holes spaced on 0.1" centers works fine. It is tedious to wire and shorts between pins must be watched carefully, but I've done dozens that way myself prior to having the PC boards.
