Pretty much what Bob said. I just screw around now and again sidebounds - and a few post season days. Lots of fun.
The biggest issue really is getting avy training, putting together a real kit, and lining up a trustworthy/sensible group. Do not skip avy 1. Do not go second rate on gear. Emergency stuff is not where one should cheap out. Then find someone with experience and a charitable bent in terms of time. Not really that hard to do. Most everyone has had someone give them a helping hand. And lots of people seem willing to pay it forward.
Oh and be prepared to feel like an idiot first time out. Skinning looks easy, but it is a subtle art. And an aerobic one. I still suck - but I am less silly than that first day. Without someone explaining where and how to pressure my skis, I'm not sure I'd have made it 200 feet. Sigh...
Lots of useful info, some more specialized, on an assortment of other sites. Check out everything from TGR to telemarktips to turnsallyear to alpinezone. Lots of valuable info out there.
Regarding rocker - I'd say so. Why anyone would search for powder on skis lacking rocker eludes me. That said, really fat skis (esp rockered) can make certain things harder under some conditions. I'd probably bias toward the S7s, but your Bonafides would probably work well. Only you will know if your biases end up running lighter and narrower or fatter and maybe heavier. If you like it, you'll probably end up with a dedicated AT/touring binding on something.
