1/4 mile ET guesses

Okay, I figured I would post this here since this thread already has my cars specs and performance numbers. I have recently purchased an MSD 6AL box, Blaster 2 coil, MSD Pro Billet Distributor and MSD plug wires. I will be installing all of this in a few weeks and was looking for some advice on wear to start with my timing. After reading the instructions I was thinking about starting my mechanical advance with the black 18* bushing and using the light silver and medium blue springs? Is this a good place to start with my set up? Any suggestions on where to try my total?

Also looking for suggestions on good spark plug brands and what I should set the gap at. As always thanks in advance for any help and recommendations.
