If the check engine light does NOT come on when cranking, at the times when it won't start, and the relays are clicking and buzzing, then your ECU is in need of repair. The engine will only start after the check engine light comes on and the ecu is what controls that. ECU is likely going bad, causing the delayed start problem typical of early 90's jeeps. Reasonably priced repair or replacement services for your jeep ECU are available on ebay.

all mufflers have a hole for moisture to drain out so they don't rot out as fast

recheck and replace plug wires.

You have a cylinder misfire. You need to check the distributor, wires, and pull the plugs because something is not firing the fuel mixture in one or more of your cylinders at timew. you can do the plugs yourself for the most part. I dont know how the 6 cyl looks in the engine compartment of the wrangler, but from my experience with a 96 XJ, number 6 cylinder is very difficult to get to because of the interior air intake vents. if all the plugs seem fine, you may want to take it into a shop for a distrubutor and wire check

Bolting it in a third row seat? that'd be fairly easy...just need something solid to anchor it to (like a thick piece of metal) on the underside to put the bolt through. do the same with seat [lap] belts and that should solve any law issues (actually some states i believe don't "require" rear seat passengers to be belted in, but I'd strongly suggest it for the kids safety!)...my big question is where are you finding enough room for a 3rd row seat? wranglers aren't exactly loaded on space...

as for torque...wrangler seats are fully removable (makes it easy to wash mud and stuff out) so as long as the bolts tighten down (air gun preferably, but you can arm twist em if need be) you'll be fine, just make sure everything is as secure/sturdy as the factory seats

Did you check the computer for trouble codes ?Did you by chance move the crank sensor ??

If it won't crank, check clutch safety switch and cables for the starter.If it cranks but won't start, you'll need to find out if it is ignition or fuel to know where to look next.

Your engine computer is going bad. There are three capacitors inside the ecu that are going bad, unable to hold current. You can replace the entire ecu or try and change out the capacitors in your ecu. It's a common problem with early 90's jeep ecu's.

check chiltons manuals, they usually have wiring diagrams in the back of them to show you all you need. its hard to find online ones. you always have to pay for those ones
