Is it best to work all the way through the rear cassette before shifting the rings or try and shift to the smaller ring half way through the cassette?
Shift the front & rear at the same time. As you drop to the small ring, drop down 3 or so harder gears in the back so you're in about the same gear, until you need an easier gear.
