If there is room to move the wheel forward or backward about 1/2", that
will do nicely. Forget, though, the tensioner. If you only have 1/4" of
forward/rearward motion, you can still make it work. You may not need
this if the numbers work out in your favor, but you can get extra
flexibility by getting a half-link. These are only available for 1/8"
chain, which you can use.

Yes. The old, non-cartridge bottom brackets use a separate lockring on
the left side to secure the left cup. On English thread bottom brackets,
that lockring will fit on the hub threads of an old freewheel-style hub.
I do suggest that a real track hub is better, but....
I recall the last BB

Should be available, but not easy to find. Easier to find an old bike --
cheaper to buy the bike for the lockring than to order it special. Seems
a waste, but you can put a cartridge bottom bracket on the old bike,
maybe.

If you are not using a track hub, which has left-hand threads for the
lockring, some sort of goop to hold the lockring and sprocket in place is
a good idea.
