I'm an atheist and secular homeschooler, and I'd like to encourage you not to worry about working with religious homeschoolers. They can give you good answers to your questions, and if you get some religious content in your readings, it shouldn't be a problem. I compromised and combined some homeschooling and some state schooling and often preferred the theistic religion of some the former to the nontheistic religion that permeates the latter. I think you should put aside the quest for "open source" curriculum and choose the best items you can find a la carte. The point of homeschooling for me, as a secular homeschooler, was to create a customized educational experience tailored (meaning adapted on the fly) to what each child seemed to need and what seemed to work. That meant not looking for comprehensive curricula but trying different things for different subjects. Keep working with other homeschoolers, online and off, to find materials to try. It's very difficult to predict what will work before you try it, because kids are so different. Reviews and recommendations help, but steel yourself to the hard fact that doing the best job will mean expensive trial and error.
