Multiple questions for Satellite

To give an update I said way back in August the tranny blew and then disappeared a while, it was rebuilt and they did it wrong so last week they fixed it so now it is in a different shop for the brakes. I have just a couple of random questions you might be able to answer.

Engine smoke:
Its been burning oil latley, is there a good way to fix it?

Body lean/twist:
When I got the car the driver side was lower than the other side. Replacing front shocks fixed it, back was slightly slanted still but not bad. Taking it back to the Transmission shop I went from Neutral to Reverse to readjust parking. When I did the shift was smooth but the body like twisted counter clockwise. Now its tilted funny again. Any reason for this?

Most likely many more to come:D
