1. Do not listen to any advice from anyone here in ski gabber. If you want instructions on becoming a trend whore, then listen to their advice. Very little people here know anything about actually skiing. Just about every recommendation is gonna be based off of hype, coolness, and xxxxl-ness. You'd honestly probably be better off picking skis based of their topsheet graphic than from some kids opinions here on NS.
2. Check out the Gear Talk forum, there are quite a few people that know their shit and will make a solid recommendation. You will be able to tell who they just trust me you'll know.
With that said...
BEFORE YOU DO ANYTHING go to your local reputable ski shop that carries some good brands and go get fitted for boots. Make sure it's not some racer jock shop either, otherwise they'll be putting you in some stiff as balls heavy forward lean boot. Ask them to size your foot for both length and width...see what recommendations they make, and if you can snag a good deal, buy the boots there. If not with your size info get them online, then take them to the shop to get baked and all that goodness. Ski boots are WAYYYYY different than snowboard boots, and if they aren't fitted properly you will hate your life, hate skiing, and not progress at all.
As for skis, scour the internet for outlet sales, bargains, etc. I don't really like buying used gear unless it's from someone I know personally. There are some great deals to be had on last year's shit.
Although you may not want to be a real skier one day I'd recommend getting a pair of stiff-ish all mountain skis that are directional and traditionally mounted instead of a flop flacid penis center mount park only ski like the anthem, afterbang, etc. They're good in the park, sort of, but those skis can be pretty hard to learn with and honestly you're gonna want to spend plenty of time OUTSIDE of the park while learning to ski. Besides, center mount symmetrical skis are mostly beneficial while skiing BACKWARDS, and you're gonna spend most of your time learning how to ski forwards first. Having a stiff, solid ski that handles well with speed and edging in a wide range of snow conditions throughout the mountain is always nice to start with. Becoming a good skier then transitioning to the park is becoming a less common thing nowadays but trust me it really helps. Park skis now are getting cheaper and cheaper so when you get the basics down...that's when I'd go for a park ski. Trust me I've skied many many park specific skis (especially lines) and in my honest opinion, a lot of them suck balls all mountain. I have a pair of afterbangs and I like them on rails, but sometimes I fear for my life ripping full speed down some groomers because they're floppy cunts with pretty much no feeling of safeness with speed.
Just my two cents, take it or leave it.
