I'm also starting with hi-resolution and got the Touch for the same reasons. You should be aware it can currently handle up to 24bit/96kHz, so depends on what you refer to as hi-rez. It won't do 192kHz, but then many who have been trying this for a while say it's difficult to perceive improvements beyond 24/96. I don't have an opinion from personal experience, yet.
My path: Touch, later add an outboard DAC. Some prefer a computer as source, others hate them vs Touch. It's a personal thing, I guess. The Touch is capable of putting thru bit-perfect info and is a nice source with a great interface.
I'm not familiar with Airport Express.
