I joined this board just to respond to this post
If you're looking into architecture AND urban planning, you should really talk to a planner about what exactly it is (unless you know and you've already set your mind)
Even THE PLANNERS THEMSELVES realize they have a boring rubber stamp job. I have to listen to Curious_George complain all the time ;) You should drop him a line, he'd be more than happy to help you out and could probably point you towards a school planning wise. Architecture wise you may need help from somebody else. I'm also looking into architecture so if you find anything let me know!
