4) If you're using film and enlarging it, the slower the film is rated (i.e. ISO 100) the finer the grain and the more you can enlarge it before the picture looks grainy. BUT, slower film needs longer exposure time / larger aperture so a tripod could well be useful but again we're increasing weight (although tripods are quite light, by the time you're at 10,000 feet EVERYTHING is heavy!)
OTOH at altitude the light tends to be very good, 1/500 sec at f/8 on 100 ASA is normal in full daylight.

5) A set of graduated filters such as those produced by Kook or Cokin will help to balance the exposure between bright sky and a duller land. Not essential but they'll help to balance the exposure. However this is munching in to the budget. But then it would be a shame to bring back pictures that are not as great as they could be from a Big trip.
Sure, but the sky is relatively darker at altitude. Definitely don't try to use a polarizer - it will look like massive overkill. You might find an 81A or 81B warm up filter useful, shadows tend to go very blue if uncorrected. My opinion on grad filters is that they aren't practical without a tripod and often don't work very well in mountainous environments as the horizon is rather jagged.
One other thing - Fuji Sensia 100 has significantly more latitude than Velvia, does not require refrigeration before and after use and may be less sensitive to X-ray degradation. You may find it more appropriate. I used to use Kodachrome 25 in the mountains - no longer available; Kodachrome 64 is too contrasty and seems prone to odd colour casts. I found 25 ASA fast enough in normal daylight.
