questions to refresh my rusty memory

Depends on whether you want an answer regarding mere numbers or useability. In either case I'd say it's a rather lucky find, quite rare and all that. The +AC% aren't that bad, the +str is almost maximum. But then again, there's the problem that it adds "only" strength (+all or +life might be more useful, depending on one's playing style, prefences and all that) and that the plate's base AC is rather low, resulting in a lower AC total which might be a problem for a warrior if he is to have high AC but no AC shield. <insert further minmaxing babbling>

Summary: It's a rare drop, at least a decent item and, depending on your style, might be very useful or not. Each to his own and all that.
