Hi
Those 35 watt headlamp bulbs are a higher rating than would have been used in 1929. The switch panels have fairly chunky internals, so you should be OK. However, for peace of mind I'd be inclined to use a suitable relay which can be tucked away somewhere out of sight.
The total load can be reduced a little by employing LED tail lights, if strict originality is not important.
Personally, I have never had any voltage drop issues when simply using the chassis and bodywork as an "earth" return, provided any joining bolts are clear of paint. It worked fine when these cars were built. It's easy to use a modern voltmeter to check the volt drop between the return of any bulb and the battery, this should be less than about 0.2 volts with the bulb illuminated.
