You should check to see if there are any state tax benefits for contributions to your state's 529. Here in NC, I get a state tax deduction on the first $5000 in contributions to the 529 so I contribute that much each year.

Don't forget about the Coverdell Education Savings Accounts. You can contribution up to $2000 per year if your modified adjusted gross income is less than $220,000 joint ($110,000 single). You have the same investment options as you do the Roth IRA. I have accounts for my daughters at Scottrade.
