Wool/Gore Tex is good - maybe consider capilene = a bit lighter, more comfortable & just as efficient as wool.
A decent pair of binoculars may come in handy.
If the weather turns real nasty, your boots may save your life = if you can't walk due to frozen feet - you're sunk.
If you're not in shape (don't under estimate a change of a mile or so of elevation as a trival thing) - you should be. A two-hour climb with no air is no fun.
