Backcountry Skiing Colorado without Avalanche Training

So I am planning on taking a BC skiing trip in Colorado soon (probably southwest, maybe Molas Pass area?) and was wondering if I have a probe, shovel, and beacon and know pretty well how to use it all but have no proper avalanche training if it is safe to ski out there? So ya, what other prepping do I need to have for safety and how necessary is the probe, shovel, beacon set up out there? (guys I am planning on going with doesn't have any of it). Also none of us have been BC skiing before, but have done plenty of extreme skiing, sidecountry, hike to's and stuff... mostly in Telluride -- we can handle the skiing no problem.
