My truck is a 2006 Ranger FX4, so I'll give you my take on it all.
I wouldn't be afraid to do lift shackles, I've been running them for several years now without issues. That is, if your leaf springs are in decent shape. Belltech 6400 is what I used. I likely would have been better off with new leaves, at the time I probably had 90000kms, but like most people, I have a budget.
James Duff traction bars made a big difference in how the truck handles, especially deep snow when the tires are spinning. A great product!
I would forgo the body lift. With the shackle and mild torsion bar crank (marginally more than the trucks original ride height spec), you should be able to comfortably fit your desired tire size. I run 265/75 R16 Duratracs on factory rims for winter, and 33x10.50R15 BFG muds on factory Alcoas for the summer. Oddly enough, the 33s fit better, the 265s rub slightly when turning (barely noticeable), whereas the 33s don't. Not sure why, it's so minor I just don't care. You will need to use factory rims, as most aftermarket rims have less backspacing, and won't fit the same.
There is a little bit of aftermarket for these trucks, you just have to REALLY look for it. C4x4 makes a nice (in my opinion) winch bumper, for a pretty reasonable price. RCI metalworks makes skid plates. I haven't bought either of these products, but have heard good things, especially about the C4x4 bumper. I eventually plan on purchasing the bumper, I just want it to coincide with a trip south, to ease the shipping costs.
Alternately, you could find OE skid plates.
Lastly, camping in the bed of a Ranger is "cozy", so be prepared and have your storage dialed in. With a sleeping platform, there is no room underneath for a cooler, unless it's one of these Coleman coolers meant for a single layer of beer cans. I have to keep two coolers in the extended cab, but I also keep my spare tire under the sleeping platform. All told, especially with the reg cab, a roof rack would probably be a good idea.
Here's a pic of my setup:
No drawers, just bulk storage. Shallow rubbermaid totes work well.
