Sounds like most of the advice is saying the same thing: The more technical the climb, the better the equipment you'll need. I don't really have any idea what I'm doing, so if you see some fool out there running around in the snow, clueless but having a good time, that would be me. Take my advice with a grain of salt.
If you're just doing local trails, you might be fine with even the light weight Yak Trax or some other simple strap on device that's not even a true crampon.
The first time I used snowshoes, I came across a person about a mile in, walking quite easily and getting plenty of traction with just boots. I found that the less equipment I wear, the easier the trip. So, now I start with just boots or trail running shoes. As soon as it gets too slippery, I put on the crampons. I stay with those the whole trip if I can. If the snow gets deep and I begin to posthole, I take off the crampons and put on snowshoes. Same thing in reverse on the way down.
One thing I would mention. I use those little packet hand-warmer things in my gloves because every time I have to stop and make a change, I can't do it with gloves on, and my hands get bitterly cold. It makes the whole trip more fun.
See you out there!
