You can't get either the leafs or the tailgate (yes, there's a TSB for that) for free, as you'd still have to be covered under the 3/36 warranty for those parts.
As has been said many times, TSB's are not recalls. If the customer complains about the truck bottoming out under load (leaf springs) or bending the tailgate too easily, then the new parts would be the solution. If nothing happens, then no free parts.
If you really hate the leaf springs, don't buy Toyota's - go aftermarket. As for the tailgate, I don't know what it would cost (including paint). The tailgate was finally redesigned a couple of months into the 2008 model year to be stronger. If you swap tailgates, you'd have to disassemble it a little bit to re-use the plastic parts and the latch mechanism on the new tailgate.
