Yes, that’s generally my order. Keeping in mind you may have a gap to fill and stain once the neck is attached. Depending on the size of the gap you could glue and shape some veneer before attaching the neck, Clou and stain after attaching the neck, or simply fill with lots of poly over time if the gap is small. The gap size is a little hard estimate sometimes from a photo.

If you’re happy to level the frets at the end, no problem. Perhaps just make sure the truss rod works for piece of mind.
