Remember also that I am assuming here that you hold most, if not all, of your securities in tax-advantaged retirement plans. Certainly all bonds should be held in such accounts. If bonds are held outside of retirement accounts, you may well prefer tax-exempt bonds rather than the taxable securities. Moreover, if your common stocks will be held in taxable accounts, you might consider tax-managed index funds. Finally, note that I have given you a choice of index funds from different mutual-fund complexes.
