Mike, welcome to our Whitney family.
I'm sure you will get lots of advice.
You have not stated your collective experience. Can you add that? It will be a lot easier for us to help you.
Don't buy low-end equipment. Your life may very well depend on the quality of your pack/tent/bag/boots. Borrow or rent until you know exactly what you want/need. Seriously.
Don't forget the trip report, and if there are no photos, it didn't happen.
