The Westmark is a great board. Solid choice there. I don't see a problem with the bindings either. Only issue is the boots. Don't just buy a highly rated boot you find online. Go to a local shop and try on a whole bunch. Boots are the most crucial part of the setup. If they're not comfortable or don't fit right, the rest doesn't matter. So in short, it's all good but make sure you try on some boots and find a pair that fit just right.
Agreed on the above.
FWIW, I have ridden Salomon boots the past two years. They are VERY comfortable. Supposedly they run on the narrow side of things in terms of fit. With the Faction, my concern would be that they use a single boa lace. Double boa is the way to go, so you can tighten the top and the bottom of the boot to your preference.
But yes, try on different brands. I'm now riding DC boots and quite liking them.
