The actual stp distance is 222.8. So, you're fine either way. 222 is the accepted distance. There is a guy KWILIS on the Vinyl Asylum that creates really nice protractors for $50. He just did one for me and it's great.
As for the wobble, That sounds like a LP pressed off center not a cart problem. I've never noticed this.
Do you have an accurate VTF gauge? And, is it calibrated. I use one of those digitals that you get on A'gon for $50 but are sold at Music Direct for $130 and it works great. But it got out of calibration and I didn't realize it. I kept having cart problems and finally I double checked the VTF and found the problem. Easily fixed.
I shoot for my tonearm to be pretty much level when setting VTA, but some carts will want the tail up and some others will want the tail down. But I'm not a big believer in this needing obsessive attention.
Getting my azimuth more or less set has made the biggest improvement in my sound.
