If it isn't a lot of dust, I'd keep it. I was in the same situation as you - my iPod had a little bit of dust under the screen (mine also had a light leak - a gap on the right hand side of the iPod where you could see the backlight coming through), and I think that's where my dust got in. I sent my iPod to Apple twice, the first time the lady I spoke to when I organised the service put down some crap about the battery as being the problem, so of course the technicians never looked at the dust.
Second time they finally did something about it, and sent me a new one. No visible light leaks, but in the week I've had it it's gotten a hell of a lot of dust under the screen, and I really have no idea now - it's so much more worse than the touch that it replaced. If it wasn't for the fact Apple damaged it when it was serviced the first time (it came back with dents and scratches), I'd have just kept the first one.

I use my iPod every day and couldn't go without it, so does Apple send me a new Touch, then I send them my old one back? Or do I send them my old one and wait for a week to get a new one?
It's pretty easy to figure out that you'd have to send the old one in first if you think about it logically:
1) If Apple sent you a new one without getting the old one back first some people may screw them over and never send the old one to them, thinking they can get away with it.
2) If Apple sent you a new one without assessing the problems on your old iPod then you'd get thousands of people trying to scam Apple by saying their iPod is totally ****ed, getting a new one, then sending the old one back just because they scratched it or whatever. Apple won't replace an iPod unless it's likely that the problem has been caused by a manufacturing flaw or something that cannot be, in any way, attributed to the owner/user; as a result their technicians must look at it to determine whether it's a valid complaint.
