Nearly finishing sanding...more questions

[Steve Mars]

As I get to the stage where I decide how much more sanding I will do I have a few questions, my build is an E-5V (based on 1940's Arch top Gibson)
1) Around the base of the neck where it joins the body how much time should I spend 'rounding off' the corners...I sort of keep looking at my 335 for comparison but given it is not as deep this bit is not really comparable.
2) I am trying very hard not to sand where the neck fits inside the body to keep the fit as tight as possible. Is that right?
3)Was planning to sand up through 600, 800, 1200 then steel wool but it seems this is not the preferred course of action? Any comments?
4)Shielding the pick-ups. Is that recommended for this model? I do want it to sound as smooth as possible a la early Kenny Burrell,Oscar Moore etc
5) When I commence the Dingotone phase am planning to hang the body and neck separately as I apply the finish for stage 1 and 2 so that there they are not touching any surface while they dry. It is then my intention to join them so that when I apply the final coat(s) the join around where the body joins the neck look like it is done as one job (again using my 335 for comparison) Will hang the guitar for this phase as well. (Yes I know I have had some opinions on this matter previously, but just in case there are any further thoughts.
6) Am assuming I apply the Dingotone to the fret board, all three stages but just to be on the safe side, is that right?

I actually hung off starting my project in case one or a couple of kids at the local high school wanted to come along for the ride and if so allow them to see the whole process...sadly had no takers...but have enjoyed the sanding process just so much, loving it and can already considering what will be my next project...of course the only problem is that it does take away from actual guitar practice, which this drummer desperately needs.

Anyway thanks in anticipation of thoughtful answers.
