Thousands of folks take off every year with a lot less planning and research than you have performed and they seem to do alright. But I'm not the kind of guy who risks comfort (and possibly much more) without knowing what I'm doing. I wouldn't start winter backcountry ski camping without some training and some experimentation under controlled and reduced risk conditions.
I strongly urge you to sign up with a supported bike tour event--tow or three nights or a week. It's an expensive vacation, about $100/day on average, but you learn how to ride distances, how your gear works, how your bike works and how to pack and set up your camp. then take a few short overnights with all of your gear packed on the bike. There are plenty of places wherever you are that you can ride to, set up camp, eat, sleep safely and return.
Or, of course, you can just saddle up and hit the road!
