I am going on a trip to Whistler (ski resort 2 hrs outside Vancouver) next weekend with some of my visiting friends from Montreal and I want to ask for some advice with my DSLR.

I am begineer in the DSLR world and most of the lenses I got are from my dad's older Canon EOS 10S SLR, so I am not very sure on which lenses would work best, I will be doing a combination of shooting of people and scenery in the ski hills. If I could bring 3 lenses with me (see equipment list below), which ones should I take, and what are the reasons for your choices?

My equipment list:
- Canon 40D
- 17-85mm f/4-5.6 IS
- 28-135mm f/3.5-5.6
- 100-300mm f/4-5.6
- 24mm f/2.8
- 50mm f/2.5

Is there any special care tips I need when I am bringing my DSLR to an environment that can reach -30C/-22F? I am sure the 40D can take a decent beating with its solid construction, but just want to make sure I am handling it properly.

I know there are lots of experts on this forum, so I apologize if any of my questions are childish...

Any advice on camera mode settings and lense choices would be welcome, thanks in advance guys!
