Seems pretty easy - pull bed off and just do it.
Yes, piece of cake on your own. I will offer this advice if you have ANY problems with the fuel pump: order a complete Motorcraft assembly from Rock Auto. Its much cheaper than at a dealer, and many have had issues with non Motorcraft pumps.

As I said above though, I wouldnt worry about idle roughness. It makes sense that an engine with no balance shaft would transmit vibrations into the truck when under load. The ONLY reason the manuals dont have this issue is because they idle in Neutral.
