Look for a good all-mountain ski. Elan and Volkl make great ski's. Technica makes a great boot. As far as stores, try to stay away from the sportchek type store. As for a good store in calgary, I would head to Techno sports, ski west or ski cellar. I am not a big fan of abominable. Everyone I have ever dealt with at those stores has been great. Very knowledgeable and helpful. They will make sure you get what you need. Good luck and have fun. Don't forget to pick up a helmet too
Elan and Volkl make great skis, but they are more of a race stiffness. My volkl powder skis are REALLY stiff compared to most other pow skis.
I came back to the sport about 3 years ago, and bought some used demo skis, Dynastar Contact 10's. I adore them, they are the perfect length, the perfect amount of shovel on the tip. They are a stiffer ski but that allows for a brilliant carving ski on groomers (which i suspect you will spend a lot of time on) and have a reliatively short turning radius. Make sure you take your weight into acount when buying skis. I am thin so I needed a shorter ski because i cant man-handle a larger ski and still have fun.
I would highly recommend finding some used demo skis in your size, and i would also stay away from many all mountain skis unless your going to hit moguls, black diamonds and places where you have sluff and powder buildup. A ski that has a thin waist will allow you to improve at a much faster rate because they are much quicker edge to edge and are more telepathic then their powder sisters. I have two sets for variable conditions. One set is a 2009 Volkl Gotama (105mm under foot, no rocker, no camber, fairly stiff "all mountain, pow" ski, and the others are Dynastar contact 10's and are 75mm under foot with a fairly large shovel at the tip)
If you are ever in edmonton, Sundance has one of the best boot fitters I have ever met. If you are going to buy any gear, MAKE SURE you are prepared to spend the most on boots. Skis are skis, and of course they all ski differently but boots MUST fit correctly. I tried on ALL of the boots in the store, all the womens and all the mens and ended up in Nordica supercharger enforcers. (annoyingly the most expensive boot on the shelf)
I still had to have them punched out and form fitted, but now I have a boot that will last for YEARS!
If you get the chance to try on some Full Tilts, do it, they are a 1980s boot design thats been updated for 2010/2011. Its a raliche flexon comp
