Your enthusiam is contagious and I almost wish I could tag along with your group, it just sounds like it will be a lot of fun. I really like the week of scouting and FISHING! Two weeks of straight outdoors a long ways from home sounds like a blast.
Reading your posts I think you'll be in plenty good shape. You can never be in too good of shape but you will need to acclimate yourself to the higher elevation and this is very critical and has nothing to do with how good of shape you're in. Just make sure you spend at least 24 hours at 7000 to 8000 ft doing very little before heading up beyond that. Don't get to your cabin and start doing your workout in anticipation. Again give your body 24 hours to acclimate below 8,000. Altitude sickness will ruin your whole 2 weeks so make sure you heed this advice.
Enjoy your trip and make sure you let us know how it goes!
