2 things I would verify: correct bulbs are installed and terminal tension in the fuse block. If okay, I would perform parasitic draw test and isolate each branch of the circuit(s) to determine exactly where the short is. Good luck
In my research a static drop using front spindles and hangers for the rear leaf springs does not affect load capability. I would inspect vehicle to make sure nothing is broke with regards to the frame or suspension as 2 inch difference side to side seems extreme. I would probably replace both...
Jack front tire off ground, check for lateral play by grasping the tire at the 12 o'clock and 6 o'clock position. Any play would indicate either worn or loose bearings

Yes they may show signs of pitting or more commonly heat damage. I always replace the bearings completely unless as stated earlier broke down on side of the road
No idea, but my thought would be clamping the springs such as they are would almost duplicate shortening it thus changing spring rate? Poor man's ladder bar?
Being that the engine runs, I would perform a compression test. Follow up with leak down test. Read up on that. Its an internal combustion engine so no special diagnosis required. Good luck
As you stated HEI would eliminate points and capacitor. I lean towards coil as well. The ignition control module typically are not intermittent, either they work or do not.
For what it's worth, the late model trucks use dual fans. With a combination of 3 relays, can actually switch the fan speeds depending on demand.
