You can just eliminate any of the original '76 alternator wiring, it is self contained on the 2002 like you said.
As for the blue wire for the '76 oil pressure gauge, you need to mount the '76 oil pressure sender in either the oil pressure sender spot of the 5.3, or you can drill and tap the block off above the oil filter, then just hook the blue wire to it and you're done.
