Help, I need to buy a torque wrench

Good point leaded one. Actually, I went to an engineering seminar years ago that discussed that. The general consensus was that the overall torque is not what's critical. Getting all of one type fastener to the same or very close value is. I've built so many engines through the years and not once have I ever used a torque sequence chart.......EXCEPT where stretch to yield head bolts were concerned. On conventional head bolts I simply begin at the center and work my way out in 3 steps. Never had a problem.
