as for coats, my insulated coat has been a little too hot for me even with vents on pants and coat open. although it's nice on super cold mornings going up the lift, I hate it by mid day. I'd look into a good waterproof shell with a nice light to mid weight fleece.
if you need gloves, highly recommend the dakine cobra. my have lasted many seasons and still in great shape. can't go wrong with leather + goretex + fleece liner.
if you need googles, spherical polarized lenses are pricey, but so worth it.
keep an eye on whisky militia and the other clearance sites owned by backcountry/dogfunk
