i believe the only difference between the x ice, x alp, and x dry id=s the color and grip, the CAMP(cassin is part of camp)
site has more info.

The sewn loops on the ends allow to create a multiple point anchor while allowing the weight distribution to adjust. Beyond this webbing tends to be more versatile and cheaper.

L/R foot is designated by the straps going to the outside; you should be able to use them in reverse if you want, but it would be difficult to put them on and off. Also some newer shoes have the foot cup more specific so there is a specific L/R.
The heal lift is for balance and foot position, critical for when carrying a pack and on steep climbs; on long days I have used the option on flats to just stretch my calves out. I wouldn't buy full size snow shoes without them, I have a pair of small rad feathers for running, but that's another ball game.

Those are the main wearing parts in new snowshoe design; the rubber straps become worn and weathered. I am on three seasons without many issues, but only use them a dozen or so times a year. I expect to need to just replace the shoe before maintenance.

It depends on your boot, but most likely yes. Just for comfort though, I recommend lighter shoes you can stop in your pack on the red down. From experience even mountaineering boots feel heavy fast in snow shoes. If the tempeature allows, I often use Saucony Pro Grid Razor winter trail running shoes just for contort. If you are not below zero, bring an extra pair of socks and go without them; they are waterproof and warm, just a low 'ankle' cut.
