That sounds about right. I'd try it with a 200 watt bulb though just to be on the safe side (or wire two 100 watt bulbs in parallel). The important thing is that you don't seem to have a dead short. Run the set like that for a minute or so, and make sure the electrolytic cans aren't getting hot. As for the tubes, they should all light up, albiet a little dimly. It depends on the set, and how much juice it draws though. I know that I've been able to run a 23" Zenith (60's vintage, tube) through a 100watt bulb and it worked, although the picture was smaller that it was supposed to be, and rather dim.
I wouldn't worry about testing the tubes just yet - they're pretty much one of the most reliable parts in those old sets! Capacitors leak and resistors drift, electrolytics dry up in storage, but tubes pretty much have an infinite shelf life, and die slowly enough that you should be able to tell what's limping by what doesn't work. i.e., your horizontal won't lock, check the horizontal oscillator tube, etc. Yeah, I've encountered bad tubes, but more often than not, it's the components connected to the tubes that go bad. Also - just because a tube is weak, doesn't mean it's bad. In some circuits and situations, it really doesn't matter if the tube is at peak performance - for example the phase inverter tube in an audio circuit.
Good luck!
