Id suggest the A pillar covers for the tweeters. They make some nice directional ones these days that let you swivel them a bit for fine tuning.

I can't help you much with the dash speakers. Anything that doesn't fit beneath the stock covers is going to look sort of crappy, in my opinion.

The rear deck has spots where a lot of 5.25" speakers will fit. The metal could probably be trimmed back a little for a slightly larger speaker without much trouble. I can't think of a reason that a 6" couldn't fit back there. There's not much room for really deep speakers because the fuel tank is just a few inches below the shelf.
