try adjusting the truss rod to adjust the camber of the neck. you can do this at the bottom of the headstock, on the exposed bolt (gibsons you will have to remove the truss rod cover). tighten or loosen it to fix the action on the dead frets.
also check that your bridge is in tune. 12th fret note should be the same pitch as the 12th fret harmonic. if that is off, adjust it at the bottom of the bridge

This. A legit set-up will do wonders for your guitar. I'm a drummer, but I play/hang around enough guitarists to know what's up. If you touch your truss rod though, keep it to like an 1/8 or 1/4 turn at a time, letting it settle for a few hours each time to make sure you don't fuck up the neck. Best to let an expert do that though. It'll always turn out better
Hands down, take it to a legit pro-level guitar shop and get a quality, well-regarded tech to set it up for you. no other option worth pursuing if you really want that guitar to sound good again. you'll likely fuck it up on your own.

That would be pointless because the refret would cost just as much as the guitar (entry level).
If you need to raise the action to eliminate buzz, but like low action, there are two solutions:
1. adjust the truss rod so that there is a slight relief (upwards bow). Loosen the strings and turn the truss rod about a quarter turn counterclockwise (never go past 180).
2. You may need a custom nut slotted to your preferred action level.
In any case, get a quality setup. Not from Guitar Center or other corporate equivalent, but from a respected luthier in your area. Ask for a basic setup and fret leveling. It should run you about $150 for both, but it is definitely worth it.
An even better idea is to buy a basic setup kit from Stewmac.com, along with the book How to Make Your Electric Guitar Play Great by Dan Erlewine. It will save you hundreds of dollars and months of waiting time, I guarantee it.
