Just a few thoughts. Even with a SYE on a 6" lift you may need a motor mount lift to solve some of those extreme drive train angles.

As for the lean... Did you tighten up the springs before you set it on the ground? If you do, you'll have a rougher ride and an uneven stance.

If you did tighten before you set it down, jack it up, loosen the bolts in the spring perches, set it down and tighten it all back up. Also, if you used the track bar on the back, ditch it.

As for the wobble, did you drill the hole for the front track bar mount on the front axle? If not, the bracket will lever back and forth and cause a great deal of sway.

Even with my 4" lift I needed to swap to 4 degree shims under my rear springs to eliminate vibration.
Make sure you use steel shims not aluminum. I purchased mine through
blue torch fabworks
here is a link - BTF Steel Degree Shims 4 Degree Blue Torch FabWorks, Inc.
