Good advice by CircleC. I agree that its great to meet someone with common interests... and it could really turn out to be a great thing. Or she may just turn out to be the greatest friend you've ever had.
I would agree that group get-togethers is a good start. It's either there or it's not. It will happen or it won't. And should the opportunity arise for the two of you to be alone and having conversation... and the topic comes up, mention exactly what you said above:
I wouldn't hesistate to ask her out normally. In fact, I've received hints from some of her friends that she may be asking me out. However, should we get involved and for some reason it ends, it might be even more devastating than normal.
It would likely mean a lot to her that you would consider that, and may explain a lot to her if she has any concerns as to why it took you so long (if it happens to)
