a "thinner tire" will get better traction in the snow because it stands up and puts more pressure in a more concentrated area than a wide and/or low profile tire. Going with a smaller tread width is not a bad thing, and even a taller sidewall isn't too bad either but then you run into clearance issues if you're lowered and such.

$140 per tire mounted doesn't seem TOO bad I guess since they are snow tires. But in my view that means like $100-125 for the tire and the rest to mount them. It seems like you could find a cheaper deal, get them shipped in, and have them mounted and save a few bucks. At $5-10 saved per tire for mounting sometimes, that's $20-40 you could use for gas, an oil change, etc.
