You ask a interesting group of qusestions.
Some others to consider before you decide what to do.
Is a sidewalk required to be out of concrete. could it instead
be made from bordered gravel. Can the high spots in the now lifted
pavement be battered or planed to make a level surface.
If you must cut roots cut them cleanly and keep the end moist.
Good luck
