PorkPieGuy just said everything I wanted to say. Having balance in your technique is often overlooked. The Stage hats are thick and I don't think the 2002 are going to necessarily be lower in volume as they cut very well. You might want to look for a thinner top hat or 14" crash to use as a top...
Nothing wrong with not using a ride if the music doesn't call for it. When I was gigging heavily with a modern dance band I replaced my rack tom with a Sample Pad Pro and my ride with a set of 18" hats.
Stain will just make the bearing edge ugly, but lacquer will build up and harden, so it should be kept away from edges. A little blue tape and you're good.
You mentioned restaining so is this kit stained? If so, that's another can of worms.
