No to everything in that paragraph.
No to using the rear except in a panic stop, or trail braking into a corner. If you want to transfer weight to the front then do staged braking. Apply a little bit of front...apply a little bit more. But I don't see the need especially with ABS. The ABS does not lower braking power unless it is kicking in to stop the tire from sliding. And the way Kaw's ABS works it is actually giving you more braking power if you use just the front, because it applies a little rear for you automagically.
And certainly no to putting air in the lines.
