Factory springs are going to struggle with steel bumpers and a winch. Having 4 door coils would likely help, though you'll want to check the part numbers on your current springs versus the part numbers on the donor to get a sense of the improvement.
The best alternative would be to simply buy aftermarket 2.5" coils that are meant to handle the weight. You could then likely sell the budget boost coils to get back (a few) bucks.
Your current shocks, if designed for 2.5" of lift, will probably do fine.
