Nice, I love reading stuff like this because it helps me to troubleshoot future issues and gets me thinking about whether I might have something going on now as well.
So far I don't have the symtoms you guys have but it still keeps me thinking. I'm a perfectionist at heart and it works against me at times (for the short term) but it always seems to help in the long run.

Ok, now that I have made the decision to replace the fuel pump, I need some recommendations on WHICH ONE to replace it with. Everything I have found from the normal parts suppliers wants between 150 and 200 bucks, and all come with a one year warranty. I also called the ford dealer and they want $441 for one 
also with a one year warranty.
Any suggestions?
Thanks,
Aaron

There are some guys on this forum that seem to like this pump....
Arizona TPI :: Fuel Pumps :: Walbro GSL392
There was also a small write up on the installation. Basically because the pump is so much skinnier that individual took some coolant pipe and cut it down the middle so that he could wrap the pump in it and put in in place of the old pump to help dampen the noise and to help it fit in the holder. They say this pump works really well, as good or better then the stock.

This is where the fuel pump belongs in the first place.
Go price a Bosch fuel pump part number 69430.
Drill out the check valve in the outlet, then weld it in as seen in the pictures.

The fuel pump is more efficient at pushing than pulling. Putting the pump in the tank lets it push, not pull the fuel and also helps keep the fuel from becoming aerated.

Think about a deep well water pump. They have submerged pumps at the bottom of the well and the pump pushes the water up the pipe and out of the well.
It's ALWAYS better to push fluid than to try and pull it.

But how much better and is it worth it in our case? Since we're not dealing with the head pressure of a well pump in our fuel system, I kind of like the idea of being able to change the fuel pump in the parking lot of a gas station in the middle of no where Oklahoma (been there, done that) without having to try and figure out how to drop a tank with 38 gallons of fuel in it.

Running that scenario through my mind, I guess I would have to find a shop that has a tranny jack.
Dropping my tank is a 20 minute affair, even full of fuel, if a jack is used.
.
But what I do is simply replace it every five years or so, I think, just to be on the safe side.

Yea, I'd rather not have to drop my tank when something get's messed up. I think I'd rather spend the money on a stronger pump that's on the frame so I can have it change in 20 minutes instead of just getting started on changing it in 20 minutes.
I can deffinately see your point but for convenience it's best left on the frame, for strictly performance then it's time to drop it in the tank.
