Prices vary by region and by condition. Pretty hard to say with authority, but I know what *I* will pay.
A 14FF rear should be around $100. Way too common (because they almost never break and came in so many vehicles) to be worth much more than that.
Leaf spring price isn't too bad, but they are likely sagged, in which case you'd need at least an add-a-leaf or zero rate to correct, which is more money. MAYBE $50.
I just bought a tailgate from a member for $75. Not cracked, tinted window. Perhaps a better deal than "normal", but still. If it doesn't work, worth a heck of a lot less than $200, maybe $50. (the sum of the parts is going to be a lot more though) You can take off the inspection cover to check. I'd assume in your area the innards aren't rusted out, that makes repair a bit easier.
You will almost always do better by purchasing from a private party. Look in your classifieds under domestic auto parts (what it's listed under here) plus all of the "thrifty nickel", "buy and sell", etc weeklys. Here, the buy and sell is the best one out there for parts. Free to advertise in, so TONS of vehicles being parted. There is likely a publication like that around you, just have to figure out which one it is.
