If the non-drive side cup has a flange that stops it's progress before it snugs up against the main bb cartridge, you will have a real problem if you ride the bike.
A couple of things:
What is the width of your bb shell and what width is the bb itself made for? Many MTB's have 73 mm bb shells and the bottom bracket must be that width. A 68 mm bb won't fit properly. However, a NDS cup without a flange may be threaded in far enough to make it work or may compensate for a ds spacer. But, 5 mm is a lot.
If the wheel dish is off, that's the first thing I'd correct. That may solve the rubbing problem immediately.
