Hi B.!
There are many Christian groups in this area. I am a member of Frisco HIS, but I have heard good things about all of the groups. Here's a list for you. Scroll down to the bottom where it says other local support groups.

I also use Abeka curriculum. We are only using math and phonics at this point, and learning science and history through fun projects and outings.
I would suggest looking into different homeschooling methods to find out what would be a good fit for your child. Abeka may not be right for him, depending on his learning style.
Here are some descriptions of homeschooling methods:

Good luck!
