If you want to run E85 after you upgrade fuel pump, fuel lines and injectors and fuel filter and it get it tuned. Is that true that you can go back and forth between E85 and 93 Octane as long as you finish using all the fuel before switch back and forth.

That is correct. You would have to run an aftermarket standalone to tune it though, as it would be a bear to keep the stock ECM from trying to trim the extra fuel from a piggyback.
