I personally use all-mountain skis which are, well, good in most conditions because I typically ski in the Midwest with trips out west. If you frequently hit powder and/or live near a mountain a pair of powder skis may suit you well either alone or as a compliment - don’t over think it too much.
I highly highly highly highly recommend taking lessons next time you get to a real mountain. They are well worth the money. I usually do a tune up lesson to start the season the first time I get out west.
I’m not sure what your budget is and your ski frequency is but if you ski a lot I’d spend the most money you feel comfortable spending and buy a great pair of boots. Rent skis for a while if you need to. Then get a pair of skis. Don’t skimp on boots. Don’t buy cheap boots. Get them fitted at a ski store by a professional. Boots make/break your ski life.
Tl;dr
Buy an expensive pair of boots, it matters. Pay for lessons. They matter. Arcteryx jackets? Not so much.
