Bare-butt potty training worked for us! We kept the potty chair close at all times and asked him if he had to go probably every 10-15 minutes to keep his mind on it (he was 2). It got him used to his rhythms, and made him more aware of what was going on. You'll probably be cleaning up pee a few times and poop once or twice - I know I did. In my experience, poop was easier - he'd feel the need coming on, and make it to the potty chair with great timing. Thinking about it, the lure of books helped too. He still sits on his potty chair when he poops and looks at books for sometimes 20-30 minutes all by himself. What a nice break!
Eventually, you can ease her into underwear (which may cause a backslide for a couple of days). We made sure to highlight what a big boy he was, and he was thrilled. The whole process took probably 2-3 months, and I think we went through a whole month bare-butted (it also coincided with a new baby, so I didn't have the energy to make the next move, to underwear). Also, when I say 2-3 months, it was 2-3 months of more success than failure. Don't let that deter you! Getting rid of diapers makes it so worth it, and it sounds like she is ready for it.
Another thing to note is that they go through lapses in interest and ability. I have no idea why, but get ready for that and don't give up when it happens: it will pass. Just don't give up. You can do it, and so can she!
