Of your two fav's, I say Grabber Blue over Black..I would do a 401A Rapid Spec interior upgrade for seat with the same color stripe.
I think the comfort group is a great option myself, but to each his own. Since your going Auto tranny, not sure if you have a gear upgrade available, but if there is one, I would add some gears...
Good Luck !
