what you are looking for is touring bindings and skins.
skins are pretty simple. things you put on the bottom of your skis so that they dont slip back on the way up. youll cut them to fit your skis once you get them.
some things to know about skins though. skinning on rockered skis = not much fun. you want as much surface area contacting the snow as possible, so you want to stick to traditional or zero camber skis for skinning. you can on rockered skis, but the more drastic the rocker, the worse its gonna be in terms of traction.
as for bindings, you are looking for touring bindings. they allow you to release the heel on the hike up, and lock them down for the descent. however because they have a releasable heel, they tend not to be as rigid or generally strong as a traditional alpine binding. so dont expect to be hucking big cliffs or landing switch like EP on em
but for bindings here you have a LOT of options
marker has the duke touring binding. its advantage is, for a touring binding. its pretty burly. aka you can ski it as hard as you could a traditional alpine binding, and its almost as rigid. on the other hand, its also extremely heavy, so its not much fun for things beyond short day trips etc. if you are planning on going on longer tours, hut trips etc, they are gonna suck because youll tucker yourself out skinning with em all day.

black diamond has the fritschi diamer binding. another solid touring binding, a huge portion of the people i know tour on these. they have a couple different varieties, a beefed up 12 din version that will sacrifice a little weight for a much stiffer/more rigid and stronger platform if you want to ski harder stuff. they also have a lighter version thats lighter, and better for skinning, but slightly less rigid and strong.
lighter version link (i think this is it)

the last major touring binding i can think of is the dynafit.
without a doubt, this is THE lightest of the bindings ive mentioned, but its also the least ideal for super hard skiing on the way down. i dont know much about this binding, but i know nomensteven has a pair and loves em. bottom line, super light, but not ideal if your looking to shred really hard.

what the kid above me posted are simply adapters, that allow you to use traditional alpine bindings, but release the heel. i know very little about these, but it seems to me that your best option would be a REAL touring binding, not to half ass it.
finally though, theres a TON of other stuff you are gonna need if you are going to start touring. before you venture out into the bc you are going to need a beacon, probe, shovel, pack, slope meter, and probably a snow saw as well. along with that you need KNOWLEGE. take some avvy classes, and get out into the BC with people who already have an extensive knowledge of how to analyze snowpack and risk on slopes.
hope all that helps
