I don't use a test record. All my records are "test records". I just play them. I adjust everything by ear.
No azimuth adjustment on a Rega arm, except via shims. The above info on checking azimuth seems right to me.
On a mid to high compliance cartridge, if the bias is terribly off, it is easy to see by looking at the cantilever from the front. If it is angled off the center by the record during play, it is way off. With these more flexible cartridges, you can check for a basic center by looking at it, and then fine tune by ear. With low compliance cartridges, it is a little tougher because it won't be easily seen by looking.
