Your ignition is more than likely fine. I can definitely say you didn't need to do plugs and wires with only 19k on it!   Wires MAYBE as rubber does corrode but some leakage isn't going to cause these symptoms.

Do a fuel filter as that's easy enough. Check fuel pressure. Take the vac line off the factory pressure regulator, plug that vac line so you don't have a vac leak while testing. Should be 40 psi. Just let it idle for this.

Check codes. You can do this with a paperclip and your check engine light. http://www.troublecodes.net/ford/ Get a clipboard and pencil, watch closely and make tally marks. This will help find a bad sensor/electrical component if the ECU is detecting it. Do this before you go taking things apart or having a repair shop start taking things apart. You don't want to just throw parts and money at it. Fortunately a lot of them are cheap if you shop around.

Certainly could have some bad fuel that plugged things up with that low of mileage. But you never know.
Also....talking about passing gear...read up on the TV / Kickdown cable adjustment and bushing. This is a stupid little plastic thing that can easily kill your transmission!!! Very easy to make right and monitor, but they have a tendency to disconnect. Pay close attention to the skinny pedal. It should have a slushy/slow feeling to it. It should not be super-easy to push down, as in a stick-shift car. If it is, your kickdown cable has fallen off the throttle arm and you need to shut the car down immediately and re-attach it. Or put the selector in "1" and limp the car home in 1st gear then fix it.

So prior to you installing the plugs it was fine? Did anything weird happen when you installed the plugs? Like maybe you dropped one on the ground, picked it up, and popped it in?  I had that happen years back when and the plug was damaged after it fell.

Double check the firing order again, don't forget you need non-HO firing order...not the 5.0 mustang firing order.. pull plugs and check the gap on them.  Take a video with your phone and post the running condition if you can.

Check the timing with the spout out.. The position of the ignition module looks off but maybe that's just how the dizzy was stabbed.

Also take the distributer bag off and separate each wire, don't let the touch other wires use wire tires as spark plug wire seperators, google

Might be an old wives tale but I never let mine touch each other

There's one thing I just found out that conflicts with what I found out at the time.  I found out at the time I changed the plugs, the spark plug gap was .50.  I looked on Cool Cats and found out it's .54.  Did I set the gap wrong at .50?

Another thing I've noticed now, as I said in my last reply that it has a tick tick tick noise.  It's more like a tap, tap, tap noise that sounds like it's coming from the left side hearing it from the driver's seat.  It's constant with the motor running.  When I give it gas, the tap tap tap sound gets faster, then slows down when I let off the gas.  It had a little ping to it before, but now, it's a clearly audible tap tap tap sound. 

Any help would really be appreciated!  :-)
