Sorry, did not see what specific questions you have. If it is just the title, low ER, low turnover, passive index funds (‘total stock market’) Split domestic/international according to your plan. Can add munis if you wish but would not do bond funds due to tax drag.
Remember that in a taxable account you get the benefit of the Foreign Tax Credit for foreign withholding taxes on dividends, while in a tax sheltered account this is completely lost. As such there would be value in having more of your international stocks in taxable and more of your U.S. ones in tax-sheltered accounts.
