Sounds like you have mostly accurate info about it. Keep in
mind that unless the tranny you get actually came from a GN,
then it won't be strong enough to deal with a 350 in a truck
without some beefing. Talk to a reputable local
transmission guy to see what's involved. Hopefully the
tranny you're looking at is the dual bolt pattern type that
will bolt onto a chevy.
The TV cable is critical, you can either use a kit or cobble
something up, but it needs to be right, and adjusted
properly (possibly using a pressure gage) for long tranny
life and good shifting.
I had a couple 200-4Rs laying around for years and finally
got rid of both of them recently...since I'm into big
blocks, they won't do me much good.
