I do the following to jack up the mains on my ES when the wings are off.  Put a 4-by-4 through the shear box under the wing bolts.  On the side you want to raise, remove the gear leg fairing to expose the under-side of the 4-by-4 near the wing bolts.  Secure a jack to the 4-by-4 (e.g., make a hole that will fit whatever jack you use) and jack it up.  Works great.  No jack points.  With the wings on, the same procedure will work with a block of wood placed in the opening to the shear box under the spar.

To raise the nose, I use downward pressure (well distributed via shot bags) on the tail.  It takes quite a bit of weight to do this, but it works.  Just block the wheels off so the plane doesn't want to move.  These strategies work for me.
