I would definitely suggest checking out
warmoth for the inlay [I hear they custom-make] and perhaps for ideas on which wood to use. The wood you choose will affect the sound, so maybe do a little research into the sound qualities of each one before choosing.
I would engrave the name on the headstock, but it could go anywhere, I'd imagine. I'm very sorry about your loss.
Electronics, I think it's more of a personal preference about the tone you get. I'm not sure about any brands or anything, but maybe first narrow down between the types of pickups and bridges and stuff, and go from there.
Good luck!
