For the first, the very phrase is like asking any Christian group in the 1700s what "rapture" meant -- we don't have an official teaching on each new phrase used amongst our Christian brethern -- for instance, when you guys argue about post-mil, pre-mil, dispensationalism etc. these are new terms from the 1800s that we don't even know, let along have any official teaching on!
The Church's policy since Apostolic times is "believe the core fundamentals -- encapsulated in the Apostles Creed now the Nicene Creed which is purely Biblical. Don't believe anything that contradicts that. Besides that, you can hold a few different new phrases" and will only deliberate when something comes of utter dispute or if something is definitely contra to the faith as we have always known.
The second point requires more time to answer in detail
The Parable of the Talents captures the stewardship/ownership scenario so if you have anything on the "official" Catholic teaching (or interpretation) of the parable, that would be very helpful.
I look forward to your further reply on #2.
