As I understand it, you can change your TSP withdrawl option once a year. So you can specify how much you want each year and then set it to zero after 3 years.
As for buying an annuity, that would be from another company. At that point you are no longer dealing with TSP and would have to find out what their terms are. If you arrange to buy the annuity directly from TSP I think they will go with Met Life. Not sure about that. Also, you designate the amount that goes into the annuity. It doesn't have to be the whole TSP amount.
