Figure out what brands the shop carries and what specific models then just do some research on specs, reviews, etc.

In terms of boots, definitely pay attention to the last and flex of boots.. Although putting someone in a super wide boot will make it comfortable in the shop, once they take it on the hill they will hate it. For flex, take into consideration skier ability, weight, and what kind of skiing they will be using it for.. Don't put a 200 pound athletic guy into a 65 flex boot

A performance fit is no different to a comfort fit - if it's shit, it'll suck, full stop. Just because someone is buying a beginner-intermediate boot doesn't mean they'll be happy with a crappy bootfitting, or that they'll automatically be more comfortable, so learn as fast as you can from the guys who know what they are doing. Until you really know your way around boots, your best bet is to measure their foot then get them virtually every pair you have in their size and just be like, go mad, try the lot on, see what feels best. At the end of the day what feels best to them is probably going to be the best fit.

Not necessarily, most of the time while in the shop a beginner/intermediate skier will say that the biggest fitting boot is the most comfortable because it is not hugging their foot as tightly. So, if you do it that way and end up selling them the most comfortable boot, their foot will be sliding around inside the boot while skiing, causing the foot to be in a lot of pain by the end of the day
