1. Best thing to do is measure it. Just take the opportunity to replace all the u-joints while it's being shortened.
2. No. You'll have to move it back some.
3. Yes. I don't know about the linkage on the automatic trucks. But I'm running a Kugel arm on my 700r4 with a 3sp column.
4. Yes, buy you may have to get the drive gears in the back of the tranny to match your tire height and rear end ratio. Bowtie overdrives can help you out real quick there.
5. Lockup. At speed, in top gear, the torque converter will be slipping more than when the engine is revved, since slip equals heat, lock it up.
6. Don't count on a mpg jump. You might get one or two mpg depending on driving habits. Do it for the lower rpms at cruise and the lower first gear.
