Sweet truck PJ....
For the remote entry, i would suggest a basic alarm system. I did a 68 with one and it worked well. for the hood, i didn't put a lock on it, but i put a pin-switch that would set off the alarm if someone opened it. it also disabled the starter too. most alarms come with that option. The only disadvantage is when people would want to help themselves to a look under the hood. it did a good job of giving them a headache.
just remember to keep some sort of access in incase you loose your keys or the batery dies. for the passenger door, i just reversed the latch assembly, and had a system set up to where i could reach under the cab corner, pull a rubber plug and pull the latch open via a lever. Pain in the a** but it worked for those emergencys that you never plan on having....
