8 to 10 weeks is typical for anything that gets a finish. Takes a long time for the stuff to cure to the point where it can be buffed properly. Trying to cheat that is the most common mistake DIY finishers make. For instance, lacquer "dries" almost coming out of the gun. But, you don't dare mess with it for several weeks.
Neck pocket fit is always super-tight from Warmoth. It's almost what I'd call a "press fit". Not unusual at all to be able to pick up the body by the neck with no fasteners. In fact, I'd be surprised if you couldn't. That's actually a Good Thing, although sometimes you can chip your body's finish if you don't line things up perfectly. I learned a long time ago to not mess around with dry-fitting the neck and taking it off - you're asking for trouble because the tolerances are right around zero.
The alignment issue I think you're showing there may be the bridge's fault. At least, I'd look at that first. Warmoth's bodies are machined on CNC mills, so if the neck pocket alignment was an issue, you see it repeatedly. Probably put them out of business as well.
