I think Alex summed it up great for you, even though it sounds like you have it pretty well figured out and don't need much help!
If you continue with this hobby for more than a couple years, you WILL end up with multilples of many things. So don't beat yourself up too much about gear decisions. Go with what is right for your current circumstance, with an eye for the future. Then make mental notes of what you end up disliking about said gear and remember that for the next time your make a purchase!
While I agree with Griz that at some point, you'll want to pick up some glacier instruction/experience and experience with elevation, it doesn't seem like you need it right now for what you want to do over the next few years. Get your basic skill set down with a local school or group and practice practice practice. When you're comfortable with the camping/climbing thing and are ready to move on, then perhaps schedule a few weeks out west and get some glacier/altitude under your belt.
Just another take on it. There are many!
