If I were you, I would go with a 3" body lift. Barring that, 1.5" billet aluminum spacer (not the cheaper painted Delrin plastic) for the front. I would skip the 2" springs, they tend to bow out.
By now you need new body mounts anyway, so, you might as well do it the right way. Buy the mounts, hardware kit, and body lift from James Duff for about $300 and be done with it. I would lift the bed at the same time with 3" tubing at each bed mount and do NOT put a beam rail to rail. As it can block access to the gas tank you just created.
Now if you do rail to rail behind the cab, it does provide a secure mount for a winch in the truck bed. Basically a rail under the bed and then a rail in the bed, with both rails attached by the same bed bolt. So, you do not drill new holes in the bed. I have never regretted having a winch in my full sized truck bed. As an example with only a 5k boat winch in my F-100, I winched a big 36"+ DBH oak tree right over, and it makes loading cars onto trailers much easier.
if I do not go with a James Duff suspension lift, since I already put in the 2" add a leaf in the back of my B2, I plan on buying something such as this:

The body lift opens up many possibilities for upgrades including later v-8 engine swaps, while keeping the center of gravity lower. What I did with one B2 I had, I added a 3" lift, then I ran true 2" dual exhausts without the cross over pipe down, each side of the B2 and they exited between the body and rear under the rear hatch. This made the 2.9L MUCH more responsive along with teh cherry bomb mufflers. Plus, gave the B2 more off road clearance (water fording) and even more important, it would not stuff the B2 exhaust full of snow (or mud) when backing forward and backwards off road in deep snow drifts. You CAN jam your exhaust hard enough off road to break the flange on your exhaust manifold ...
