Answers,
1. Sanding steps don't matter unless you want that to be your final finish.
2.You can start with tripoli after 600 grit wetsand.
3.Very little will happen if the compound is worn, or there is not enough on the wheel. You just won't see much of anything happening to the part. Medium pressure to load the wheel, probably 5 lbs. pressure for all compounds but tripoli. Tripoli may require more pressure or wheel speed to load.
4. If done correctly, there will be no compound residue at all on the part. I don't worry too much about that until the final step. Just clean it really good in between steps with laquer thinner.
5.I cut one angle, then come back over at a 45 degree angle. Some people disagree and say buff only one direction.
6.Laquer thinner or acetone will work better than mineral spirits. Laquer thinner is what I use, on a cotton terry cloth it just melts the residue away. A propane torch probably won't burn any significant amount of residue off of the part. Submerging the part in acetone would probably be the easiest way to clean, and then spraying it off with water afterwards.
7.Yes, every wheel you use will turn black and stay that way.
You say it gets cloudy right? You need more speed and pressure then. If you stay on it long enough, the cloudiness should go away. If the part is aluminum, it may be conducting all of your heat away from your buffing area. Therefore you should use more speed and pressure to compensate.
I'll go take a picture of what the metal is supposed to look like when it is done.
