First get acquainted with the homeschool laws in the state that you will be living in. You can find laws for all 50 states at http://www.hslda.org/laws/default.asp
I would also get to know your son's learning style. Some kids love workbooks and others would fight that method and may need a more hands on approach. Here is a site that gives an overview of the various homeschool methods out there. The key to success is finding what method works best for you and your child.

I wouldn't get too caught up in accreditation. There are public high schools across the nation that are not accredited. Most people assume that if it is a public school that it is accredited. Accreditation is done via accreditation agencies, not the federal government. Here's an article that speaks on that http://www.thehomescholar.com/recent-articles/accrediatio...
I have homeschooled for 13 years now and my oldest 2 children (ages 19 and 21) had no problem getting into their college of choice with their homeschool transcript. I realize that this may be years off for you, but sometimes this is still a worry for some parents when they're considering homeschooling even when it is years away.
