I like to start on the desktop but build in a way I know the objects will flow. Then I set up a tester with a bunch of breakpoints and check as I go and make micro adjustments to each element that is "off". Then you can set the element inspector to the side and just keep shrinking the screen to make sure nothing is awry as the width gets less and less. I don't really have X sets of 'rules', just elements adjusting at the point it feels right to adjust them.
