Can I transfer my existing Coverdell education savings accounts and U.S. savings bonds into a 529 plan?

Yes, you can accomplish these transfers without triggering tax, but you should be careful about ownership issues. For instance, the Coverdell ESA (formerly the Education IRA) is effectively owned by your child and so it may not be proper to transfer the funds into a 529 account that is owned by you. Also note that the tax-free transfer of U.S. savings bond redemption proceeds into a 529 plan requires that you meet all the qualification requirements for the education exclusion, including the income limits in the year of the redemption.
