I took at quick glance at this write-up and got to work today.
Piece-O-Cake
You definitely do not have to take the rear wheel off to do the rear sway bar.
Just take your time and when you are under the car, swivel the passenger side towards the rear of the car and slowly start getting the curve over the exhaust pipe. Once you get a little ways over, it comes out just fine.
Putting the new rear sway bar in is just reversing the steps
The install notes for the Hotchkis front sway says to use a 14mm socket to take off the nuts for the endlinks, mine were 17mm (2007 350z) just as the OP noted.
I set the front at full stiff and the rear in the medium (middle hole) setting. You can definitely notice a difference in the (lack of) body roll in the corners now. I'm going to have to go corner carving tomorrow and see how well it tracks in longer and tighter corners
As far as ramps go, you don't need any for the rear, just jack it up from the pumpkin and then put your jack stands at the jack points.
For the front however, you would need a looong jack to reach the jack point.
So I drove up on my ghettos ramps (3 1x4's, staggered and nailed together) and then I could get the jack far enough under to reach the jack point.
I have Rhino ramps, but they don't work once your car is lowered, so I may have to try this next time so I don't look so ghetto
