Q for Bob M or others - diode in 3-wire, starter s

I want to switch my one-wire Delco 10-SI setup to a three-wire system on my '47 H. I don't have a key ignition switch - just the start button and the shut-off switch. To make the change I'm thinking I need to:

1) Wire the '2' terminal on the alternator to the 'BAT' terminal on the alternator with a 16 or heavier gauge wire.

2) Using 16 or heavier gauge, wire the '1' terminal on the alternator to the same side of the shut-off switch that holds the wire that runs to the '+' pole on the coil. Would it make sense to wire both a diode (Radio Shack PN: 1N200X - where X is 1-4) _and_ a warning light (bulb# 161, 194, 1813, 1815) in this line? My primary concern is to avoid running down the battery but having the warning light as well would be nice.

I was also wondering what the benefits would be to wire a solenoid in between the plus terminal of the battery and the starter. Currently I have 4/0 copper cable running from both the plus terminal of the battery and the starter to the start button. Putting a solenoid in would cut out a two or three feet of cable but, with that size cable already in place, would it make much difference?

Thanks for your time.
