This is a great idea and very timely. I can't wait to see what you decide on.
For the collar: keep it simple. I think a semi-gloss or glossy black paint would look great! If you wanted to jazz it up, you could always go with white stars around the collar on top of black paint (kinda like some of the vintage styling I've seen: http://www.andstillclothing.com/shop...ran_crew_1.jpg
For the taps: Keep the taps off to the side of front of the keezer. If you did stars, you could place the taps in the same spacing as the stars.
For the drip tray: As long as the vinyl wrap has the player on the opposite side as the taps, then I wouldn't worry about it. Besides, a nice drip tray always add class.
I think the real question is: Do you find some sort of Ravens sticker and put it in the drip tray ...
