6.2L Newbie

6.2L Newbie
I just got a bus with a 6.2L in it with 262,000, I am new to Diesels but have worked on Motorcycles and gas cars/trucks for a while. Since it was a bus the governor is quite aggressive, I can barely get it to 60MPH. A few questions:
1) What can I do to let up on the governor to get more out of the motor as is?
2) There is a cheap GMC pickup truck for sale locally with a 6.5 in it, would it be worth purchasing to rebuild the motor and swap in?
3) Any special tools I should get right away to help?
I will be converting this bus for a travelling Band, cargo, bunks, RV style. I need it to climb hills and run for 8-9 hours at 65-70 with no issues. I am sure there are a pile of articles on here that detail the items I need to look at but a point in the general direction would be great. Or any general opinions on where I should start on tuning this motor up a little better.
Thanks, I hope to learn and share as much as I can.

Thanks for the info. I have been digging around in the truck and making notes. I think I am going to take it in for a PM locally and have them go through some things.
I have already fixed the charging issue, bad battery balancer. I also tightened up some things, fixed the gear shift indicator, etc. I have two GMC service books now so I can identify what I am looking at as well as begin getting my hands dirty. I think the rear end ratio needs to be dropped for highway driving. Best I can tell I have a 4L60E Hydramatic with overdrive. This picture looks like some aftermarket overdrive, can anyone chime in? Maybe just a different transmission yoke I haven't seen before:
