My best advice to you is that planning is fine if it makes you feel better, but you have to expect those plans to be utterly wrong by the time you get there, too.
You don't say what your DD's complete scores are, but if her verbal is lower, than I assume her nonverbal score would qualify her as HG+, and we usually say around here that if you find a good fit for an HG+ child for 6mos-1yr., then you are doing pretty well. (And I suspect that holds true for MG kids and below as well a lot of the time, too!) But you can often expect that good fit to fall apart about that time. The perfect set up usually only stays perfect for a little while and then you have to change everything, so trying to plan the high school path for a 5yo sounds like sheer madness to me! (No offense intended there.

)
Take it one year at a time, see how it's going, and adjust as needed. Keep your options open as much as possible, and keep your eyes peeled for new options. You never know what your child will need as she develops, and you never know what changes will occur around you--new schools, changes in the existing schools, etc.--as you go along.
We started at public school, switched to homeschooling, considered a private GT school, and have no idea what we're doing next year. Our son is 7!

Take it as it comes and it seems less scary! Honest!
Best wishes to you. It's an exciting ride!
