I'm guessing you got some less than positive feedback because your first post mentioned how much you knew about backcountry 'safety', but your vocabulary demonstrated something different.
Stoked you wanna get back there. It's gonna be tough. You'll love it. You'll know you like it, but you won't know how much until you spend 20 minutes in a lift line and end up sitting next to someone telling you how hard they were killing it. Then, all you'll think about is being alone on a ridge with your friends.
Start with your avy 1. Bob Peter's links kill it. It's not super close to Red Lodge, but Exum Mountain Guides are a good place to get your avy 1. http://www.exumguides.com/winter/avalanche.shtmlavalanche.org
is also a good resource. You can find incident reports that are a good teaching tool. They are a much better teaching tool if you've been through your 1 and can recognize mistakes/red flags. It also has links to the avalanche forcasting centers around the country/world. The avy forecast is a good tool
to check before you go.
Montana has a fairly unpredicatable snowpack. Definately get your Avy 1.
You will also need to spend some money on gear. You're gonna need a beacon $300-$450, a probe $30-$90, and a shovel ($50-$100) at the very least. Sounds spendy, but you won't ever think about it if a slide happens. These things are only useful if you practice. Jackson Hole has a great beacon practice area.
Plus touring gear. You can get away with alpine boots, skins, and trekkers on your lift riding skis for the first year. But you aren't gonna like it that much. If you want to give yourself a shot of liking it, you're gonna need a dedicated backcountry set up.
Definately don't be afraid to turn back if conditions aren't right. I've walked off more than a few hills. It still counts as a good day. The dogs had fun. I still got some exercise. I was still up in the mountains.
Oh, and if you happen to be snowshoeing at first, do not
boot the skin track.
The first coupla years will be a pain in the butt, conditioning-wise. Then, some crazy sick sort of feeling will come over you, when you actually like the climb as much (okay, almost) as the ride. After all, you're gonna be skinning more than skiing, you better embrace it.
