Re: scared to, but kind of want to..
I would get her another bed. You're going to use it eventually anyways. If she's crawling all over and disrupting everyone's sleep, that's a good indication that she might be ready for her own spot. You will know when it's time.
I don't think that 12 months is too young if she's eating a lot of solids during the day. We nightweaned at around 14 months and stopped co-sleeping at 18months, but I should have stopped co-sleeping a lot earlier. Same thing, he was so wild in the bed and we all got no sleep.
