Whether you bring up all the bad stuff that you can't seem to forget or not depends a lot on your friend. How is she going to deal with it ? And do you think that it will really help you to forgive? I you think she'll be willing to explain herself in a way that will make you feel better about the situation then give it a go.
I don't know you or your friend but from the information you have volunteered, a safe move would to talk about these new discoveries with a neutral acquaintance, just to get them off your chest. If your friend has genuinely changed for the better reminding her of the mistakes of the past might not be a good idea.
(In my head you're a snowman and she's a carrot that got rolled in flour, then the melted water of your friendship washed it off her.)
It's your call dude, but even if you make a mistake, if she's your friend, you'll be able to forgive and and accept her, creepy dangerous past and all.
