Hi Grubsta, looking good.
If mine, I would stick with the cream plastic bits that came with the kit as they are similar warm tones that should compliment stain colours and feel black may be too stark. Soaking in tea or coffee would darken them up a bit if that is what you prefer.
With DT stain running low best to make a start on the neck and if you run out maybe double up with extra intensifier coats. From memory it looks like a maple neck so that will probably need several more coats to dial in a similar colour to the body. Intensifier can add some colour, just not as much as the base stain.
Cheers, Waz
