So, I used a flat-flat (home-remodeling-style) nail-puller/pry-bar and was able to pop the door-panel off pretty easy! Only three of the 6-7 clips are broken (and may already have been that way...)
Any way, prying and banging and pulling and hammering and eventually I noticed that it was the lock/unlock-pin in my case that wouldn't unlock the door all of the way! After simply pushing the lock-latch inside there ALL OF THE WAY toward the unlocked position with a screwdriver, I was able to pull the door handle and she popped right open for me! WD-40ed the crap out of it all and just played with it a bunch - seems good now!
I can also see where the two bolt-heads that hold the latch in place, as well as the little lever for the child-lock has been scraping the door-jam (due to the door sagging)! For now I just heaved on the open-door a bit to sorta "bend" the entire assembly upward on both doors and now it all seems good again!
With that done, I am inflicted with a terrible case of the "while-I'm-in-here" disease! I am going after the "bad window-regulator" on this door - I'll start a new thread!
