6' length of 1.750" aluminum that I am going to use for the connector 
for the two 7' pieces.
  Now my question is this; how long should the 1.750" piece of aluminum 
be for the slice of the 2" pieces?  I think having 3' in each of the 2" 
pieces is
overkill and will add weight to the device. I was thinking more along 
the line of 4' section which allows 2' in each of the sections. Or 
should I go with 3' on each piece?

Having worked with these things for years, I wouldn't use a 2 piece gin 
pole except for very light work.  2nd I would consider the smaller 
inside splice to be too short.  The first question is what alloy and 
temper is the tubing and splice?

I use 12' and 24' sections of 6061T6 with 1/8th, 3/16 and 1/4 inch wall 
depending on the load.

I would ask an engineer about the configuration you are planning.

Climbing and using gin poles in tower work is quite dangerous!
Every year we lose a number of well trained and experienced climbers. 
When something breaks up there your only thought is to get out of the 
way with out getting off the tower.

Working on a 40 or 50 foot tower can be just as dangerous as working on 
the big ones. You are just working with smaller stuff which can be just 
as deadly as can a fall from that height.

Be careful
