I'm hearing more and more people have their palatal expander along with their braces, I'm having mine done in two completely separate stages - mainly because I do have a very small mouth and very small teeth, it'll be easier to deal with braces once there is a little more room for movement. I also have to wait for my insurance to fully kick in (Jan 2008) before I can get the full treatment, but the expander is managable and will ensure I've met my co-pay when its time for the next phase (I'll get a phase one to phase two credit for my treatment and have covered my co-pay entirely)
I'm nervous of how much it is going to hurt, so I'm planning on having it adjusted very slowly over *hopefully* eighteen months to two years before getting braces...but we'll see what my ortho has planned. He knows the situation with the insurance as we work for the same employer, and I know he'll be planning my treatment with that in mind.
I imagine the expander is sore and uncomfortable after its been keyed, but I've already been through one round of ortho as a young teen and had an expander, although it wasn't bonded and I know this one will be. Funnily enough I don't remember any of my ortho being all that painful, just a little uncomfortable after adjustments and tightenings.
Good luck with everything, and I'd love to see some photos of the expander that you have. I've seen one on a model, but never one being worn live!
