Your first picture above shows the chainrings very close to the stay. It may just be the angle of the picture but if this is accurate, you may have your bottom bracket spindle reversed (assuming it is asymmetrical). The end of the spindle with the longest length after the bearing race should be on the drive side. Also the lock ring on your adjustable cup doesn't look like it's seated firmly against the shell. If the cup then becomes loose, it could contribute to the sort of problems you've described.

Looks like you have a lot of things to sort out. Work systematically.
