I just picked up a 2-1/8" (54mm) socket for my flywheel nut.  Didn't pay
attention and got a 12 point socket.  Is this okay for the 350 ft-lb of
torque or should I have a 6 point socket?

Sure it will work. You will need a long lever arm (6 feet) or a 3/4 impact
wrench.
Probably a lever will be easier on the nut.

I get the impression that the torque on the flywheel nut doesn't need to be
real precise.  I was going to weld an old socket on the cheater-pipe so I
could use my beam torque wrench and get a reasonable measurement of the
torque on the nut.  Are you guys just leaning on the pipe and calling it good?

There is a torque spec somewhere on it I am sure. But like all torque specs
it depends somewhat on the lubrication used. I'll check the 94 shop manual.
290 to 360 foot pounds with thread locking compound and sealant on the nut
contact surface.
