Bottom line: It went fine. I crosscut the bottoms using the old "slab of foam insulation on the floor" technique. For the rips I used a roller stand on the infeed and my router table as an outfeed table. I built the router table at just the right height to serve as an outfeed table. I fed the pine doors standing in front of and to the right of the fence, with a constant force in toward the fence. My friend guided them at the outfeed end.
Before we cut the doors we practiced with an old hollow-core door that I had around.
"If you don't practice on scrap, you're practicing on your project," as they say.
Thanks to all for the various kinds of advice.
