SP 500 is OK as substitute for total us stock if total us stock is not available to you. If you want some bonds it doesn't matter whether they go in TSP or traditional IRA.
You can use I-bond and pension for "bond" portion of that portfolio. So the question becomes whether OP wants to include international fund. My exp with internation funds over the years is that it can't keep up with US companies
