First, ignore people who say it's too old or too expensive. They don't have the knowledge or experience with older vehicles. Since you stated you have mechanical aptitude this makes life cheaper than the "lets take it to a mechanic" crowd.
Parts for that van are cheap and plentiful. You can replace the complete steering, suspension and brake system for less than $2000 and you would essentially have a brand new vehicle with upgraded parts.
The 318/360 is near bulletproof. If you have battery power and fuel it will likely start. Do yourself a favor and rebuild the carb, that will save you some future headaches. Or throw on an aftermarket carb like a 600CFM Demon. If you're really adventurous go to a wreckers and pick up a magnum engine and 4 speed trans from a 93 or older dodge truck or van. That gets you fuel injection and an extra gear for added mileage.
A bushing kit for your van is $80.
Note - It is usually not good to post VIN's on the internet. Just something to consider
From the VIN it is a 1987 base model B250 with a 318 powered by CNG. CNG? If this is a CNG vehicle you might want to talk away. CNG has Multiport Fuel Injection which is nice, but also has massive compression in the tank which after sitting so long will likely no longer hold pressure. You would be looking at complexity with the CNG and as a lover of old vehicles, this complexity isn't worth it. Unless of course you swap it out for the magnum engine mentioned earlier
