That's be ok, too, Slag. Past simple plus past simple gives us a series of actions, one after the other in the order they are said / written. Past perfect may come after past simple syntactically as in "Before I moved to Paris I had lived in London for 10 years" but is still understood to preceed it chronologically. Since both mean essentially the same thing here, in this case, I think it would simply be a subjective style choice as to which form to use.
