going back to auto and paddle shift, need advice

[dusterbd13]

im thinking about going back to an auto in my truck. i had a 700R4 in it, and never liked the way it shifted. when it died, i swapped to a five speed. now that my knees are getting really bad, im thinking about swapping back to an automatic. that way i can still enjoy my project after surgury....

anyway, i drove a C6 vette with paddle shifters. that thing was a hoot. im running a 60 degree v6 from GM (2.8, 3.4, n*) so my options are 700r4 and 4l60E that i know of. i have seen paddle shifter setups for both of these transmissions.

i am running a 7727 ECM from a 93 vette, so i believe that it has the programming to operate an electronic trans. not certain, though.

so, my quetions are:
1. will a paddle shifted older automatic operatle like to 08 vette paddle shifter setup?
2. which trans will get me there?
3. what mods do i need to make it live on track and street with the paddle shifter?
4. what else am i gonna need other than the obvious?
5. how much should i be looking at spending?
