I don't know the specific churches in your area, but I'll suggest looking for one with a great children's program. Look for something with a good youth director and a good teen program, even if your kids aren't that age yet. I think if a church has an active teen program it says alot about the youth program in general. I will suggest an ELCA Lutheran church - a little more liberal than Catholic and at my church we have many folks who grew up Catholic, it seems to be a good fit.
If you are interested in a women's bible study, try BSF International (there's a website). BSF stands for Bible Study Fellowship. I know they have a Wednesday morning group in Maple Grove or Plymouth. It's non-denominational and this year they are studying the book of Matthew. They have a children's program so you can join the adults while the girls would be with the kids, who also learn about the bible. For those in the northern suburbs, there's a BSF group that meets in Coon Rapids on Wedsnesday mornings also (9:30am-11:30am).
Don't feel bad about not being at church for so long, I think it's pretty normal! At least I can speak for myself and say that's what we did too, and I love being back. Sign up to help teach Sunday school and you'll get right back into the swing of things. Good luck - visit many and join the one that feels right.
