Taking the bed off isn't to involved. A breaker bar and a few extensions will make quick work of the bolts that hold the bed on. An impact wrench works very well also as the bolts can be VERY stubborn! Apply some grease to the bolts before you put them back in to make installation easier. It will also protect them from corrosion and make them easier to remove the next time... Make sure that you remove the bolts that hold your gas filler neck in place too. There should be a ground wire there also bolted to the bed in additon to the one dropindaS-mini mention for the tail lights. One other thing on the wiring for the tail lights, make sure that there is no plastic clips snapped to the wiring harness. These are usually pushed into the frame and they snap around the wiring harness. Before you reconnect your ground wires, sand or grind the metal slightly and put some silicone grease on the bare metal. This will assure that you have good grounds and a happy electrical system

. When you lift the bed off, make sure you have somwhere to put it (duh). Sawhorses or two steel 50 gallon drums work well. You don't wanna scrape up your paint/metal do ya? In closing, this is based on removing the bed from my syclone to upgrade the fuel pump since the lines aren't long enough to just drop the tank

so, some of the above may not appy to you. Not sure about how many people would be necessary to lift it off as we used a 10 ton overhead crane to take mine off
