Colorado Growers Unite!

Whats up.
Im pretty new to these message boards and reefer in general. i live with my parents and I was thinking about growing somewhere around my house. My altitude is approximatly 8,000 ft. in the foothills of denver. I have never grown before. I've read the outdoor growers guide snooped around a little bit online but i was looking for a little more info. here are some of the unresolved issues:

1. I have the ability to grow on any side of a few mountains around here, so i was wondering which sides (north, south, east, west) would do the best.

2. What seeds are good for a high altitude and bud quickly, yet are of high quality?

3. I have a friend who is willing to start the seeds for me and i was thinking about planting sexed females. good idea or not?

thats all i can recall as of now. All responces are appriciated thanks
