I don't know anything about the back child support issue, but I agree that you should find out now rather than waiting 2 years, especially since there's a baby on the way. It sounds like she needs some guidance and a positive role model. If she is your daughter, I realize it's a lot for you to get involved with and take on, but depending on the extent of her mother's involvement and their relationship, somebody needs to make sure she's getting prenatal care and help her have a healthy pregnancy. She may be eligible for WIC or other assistance and it sounds like she would benefit from parenting classes. If she can't handle a child, maybe she should consider adoption. I'm sure you can find (or another responder might be able to recommend) organizations that can help out with baby gear and clothes. Good luck!
