I drew all the plans out by hand from templates sized up in photoshop to the right dimensions, then printed off the PC. A scale pdf of a replacement ricky scratchplate helped me check the size and scale up was right, together with the neck length / scale length data. (33 1/4" scale is quoted, which is a bit odd and means I end up having to slot the fretboard myself )A couple of scans from the pages of a favourite guitar book helped too.
Finish - I have some black acrylic rattle can paint left in the garage and some white binding, so i may as well go with the classic. This is after all my homage to my childhood bass legend, Geddy Lee! (even though he has now deserted to the Fender Jazz side).
I will lacquer the black painted body with Rustins 2-part plastic coating (UF resin).
The neck will be 2-piece maple or 3-piece maple/walnut, depends if they have thin enough pieces up the timber yard. Rosewood fretboard (just ordered).
Not sure I'm up to the MOP triangle inlays but may settle for MOP dots for fretmarkers.
Xanthus - if you want I can send you my scaled-up photoshop image I used to trace out the bass dimensions.
