The more you work on it, the better of we are. Not too many V8 owners out there.

There should be enough room to just move the wires and lines out of the way. A 6" extension usually helps. Put a light coating of anti-sieze on the plug threads.

Torque value? 15-18lbs, quite light. I usually ignore the torque and just tighten to snug.

The loom cover for the injector wires is that flimsy plastic junk and you should consider getting a nice, colored, vacuum line to hose the injector wires. Just slice it lengthwise, put a notch in the hose where the wires come out, and the wires will be nicely protected. Red or yellow silicone would make it look nice.
