a. Yup. That's true of a lot of stuff, not just cards. In the past year or so, the GMs have been tackling the problem, sort of - there's a thread in events section to report bad descs, and they periodically fix them. Also, if you're playing on classic, be sure to use the classic DB - the iW DB defaults to renewal.
Typically, with old items (most cards, for example), iW is a better source of information than the item descs. iW coverage isn't as good for some of the newer items.
b. When you right-click the armor, it should show a red orb where cards normally show up.
c. You're on vista/7/8 right? Sounds like UAC garbage. If you're on renewal, install RO outside of program files (or other folders windows considers special) and it'll fix the setting save problem. I don't know what the current state of this is on classic - classic might need to be run as admin to make those settings stick.
