Okay. Went and bought the throttle body cleaner. The Motorcraft filter was out at AutoZone as well. Maybe a shortage in my area. I'll check the other stores in another day or two.
Anyway, got home and removed the throttle body. Dreadfully gunky! (See pic below)
Emptied the whole can of cleaner on this thing. Much, much cleaner now. Reassembled everything. Disconnected the battery again for about five minutes, then reconnected. Turned the key to the accessory position for about a minute before cranking.
Started out pretty rough, then rpms went high for a minute before settling down for another minute. Then the rpms dropped to 350ish and back up around 800. It did this for about five minutes before finally settling around 750 rpm. A drastic improvement.
However, when I put it in gear it makes a horrible rattle sound when I give it gas. Took it around the block and it went away once at a higher rpm but eventually was present with every acceleration, forward and reverse.
But it doesn't do it when it's in park. :/
And perhaps this is another symptom. Before the idle finally settled (before I drove it), I noticed a wet spot from the tailpipe. Backing up from the truck, I noticed another wet spot and drip coming from the catalytic converter, as well as exhaust coming from it, which indicates an exhaust leak. (See pic below) Seems I read this can cause misfires for some reason, but not sure if it can be related to my other problem. What are ya'lls opinions?
Thanks!
Sorry guys. Just realized I called my muffler the catalytic converter. Think I just had catalytic converter on the brain because I read about the misfire problems and got tunnel vision.

Bad cam phaser on the passenger side. Looking to get the whole timing job done now. My mechanic can't (or won't anyway) do this job, but he recommended replacing the solenoid with a different type of solenoid, I think he said non-adjusting or something of the sorts. Know what he's talking about?
Anyway, thanks for each of ya'lls help. And next time I'm in Joplin, I'll give the Red Onion a try. Think I recall seeing it on google but haven't given it a try yet, but will next time I'm there.
