Actually it's the upper strut mount you flip over. You have to drive out the studs and use bolts in their place, as well as add some washers or spacers between the strut mount and the frame to keep the strut mount from crushing as you tighten it down. It's easy to see what I mean when you are looking at the strut. Since you are changing the strut mount's position, even slightly, you should get the alignment checked afterwards.
As for the coil spacers, I run the same size front and rear spacers. Any extra height I picked up in the front from the IFS arc was balanced out by the weight of the bumper/skidplate and winch up front...
