They only care that you have your ratings and flight time. 61 or 141 is completely irrelevant (despite what many large 141 schools tell you
).
Any leadership experience can be beneficial, but more at the major airline level than at the regionals (they can't be too picky nowdays). Also be aware that other applicants will have led people in flight operations and/or combat, so the office job won't carry a great deal of weight.
