Saw it as her begging for attention, and one thing led to another. Idle is now about 750-800, where it sounded the best (hard using the tachometer, but first time and much better than fiddling and guessing).

Did the idle speed change from before your trip? Sounds like you have it properly adjusted, but I'm suspicious that the muddy drive may have thrown mud up into throttle linkage which is causing some binding.

Yes, all those connections need to be tight, using the proper fuel-type hose clamps. Diesel fuel glows under a black light, so once you think you've fixed the leaks, clean off all the areas that have fuel, then use a black light to check for leaks while the engine is running and after you have driven for a bit.

If you have some microbial growth, you need to get the proper "bug killer" to dose the fuel tank. The fungus lives in the water in the bottom of the tank, and eats the fuel. The colony can get quite large, and if too big the best course of action is to get the tank cleaned. Start simple/easy/cheap, get Biobor (or similar) from a marine goods store (West Marine is a national chain) and follow the directions to dose the tank.
The fungus will die from the Biobor and may clog your fuel filters several times as they are flushed out of the tank. You probably should carry at least two sets of filters with you (and the tools and rags to change them), and be prepared to change filters on the side of the road.

There should be two fuel lines in the engine compartment, and they should both attach to fuel tank connections at roughly the same area. The vent line is short, only visible under the car at the fuel tank, and has a little cone shaped end. Mud-dauber wasps can build a nest inside and clog it up, or maybe driving on muddy roads???

Not sure what you've got in mind here. The biobor is added via the fuel fill opening. No need to add lines anywhere to treat the fuel tank, unless you plan to pump all the fuel out, run it through an external filter to clean as much of the dead fungus at once as you can (to prevent road-side filter changes). That would be rather a pain to set up, but possible.
