From my personal experience, I set the cab first, however I do not tighten anything. I then follow the list below:

inner fenders
radiator support
outer fenders
grille support
grille assembly

After all of these parts are loosely hung, I check alignment and commence tightening fasteners, starting with:

cab supports
inner fenders
radiator support
inner fenders
outer fenders
grille support

I then install:

hood
doors
cowl extensions
firewall cowl
bed
tailgate
glass

After all the sheet metal is correctly installed, aligned and tightened, I follow with the underhood trim, interior trim and the exterior trim.

I hope this quick synopsis is helpful. There are numerous small tasks along the way, however, this is a broad brushed summary of the process that I have followed with success.
