endurance training and where to climb?

my goal this summer/fall is to climb outdoors once a week or so, join a climbing gym some time this winter and then get ready for some '06 spring climbing. i'd like to do more. hopefully i can meet some people to climb with.

until i join a gym or start climbing outside more regularly, i've decided to to try some endurance training exercises i came across online. it's a ten week program. this week i've been working pushups, plie squats, reverse dumbbell wrist curls, and pronators. since i don't have access to a gym at this point, i've been working on pullups as well. i've also been spinning at 24 hour fitness 3x a week for about two months now to make the heart a bit stronger.

today, my height is 5'8, and my weight is 138 -- i need to gain some weight! speaking of weight, i recently bought a box of oat-rageous health bars by promax. Pretty good mix of carbs/proteins/fat. yum too.
