It is amazing what putting a guitar together can teach you about getting it to play right. Years ago I bought a cheap Chinese bass (an SX) as a platform for experimenting. When I got my first kit, and used the SX as a test bed for the setup I wanted to do on the kit guitar, figuring that I could not hurt the SX too badly. Not only did I not hurt it, I got the SX playing so well that I have been upgrading it ever since. It now plays and sounds great...and I have further mods in mind ;-) I got advice about every part of the setup here. It's a good formula. Work slowly, get advice, try what you've read about...if it works voila! If not come back for more advice.
I think you also have to credit the folks who developed these guitars. The bridges and truss rods on Fenders and Gibsons are mostly very easy to adjust with very few tools. I often think this was a big part of Leo Fender's genius.
You picked one of the higher degree of difficulty guitars and got a great player that looks awesome. What could be better ;-)
