Your last question is the most important!!
Tripod, tripod, tripod!
When it comes to binoculars, whether you use $25 Bushnells or $2500 Swarovskis, a tripod will ALWAYS allow you to glass longer, and further, while discerning more details. I truly enjoy sitting behind the glass and plan my hunts so I can. I would just as soon leave my food and water at the truck as my binoculars and tripod.
When it comes to binoculars, for someone who doesn't use them all the time, there is no reason to spend the big money for Leica, Zeiss, or Swarovski. I suggest you look at Vortex. Their Razors are less than $800, and their Vipers are less than $600 depending on model and magnification. They seem to be the best combination of quality and price.
Of course, there are many binoculars on the market... the most important thing is to choose a pair that feels good in YOUR hands, and that YOU can see through well.
P.S. For glassing above timberline, I would stick with 10x magnification. With 10x you have enogh magnification for most longrange glassing and enough field of view for use down in the timber.
Give the guys at the Outdoorsmans a call. They carry both the Vortex binoculars and Bogen tripods, plus they are sponsors of this site and they are all hunters and shooters!
Good Luck!!
