I don’t have any recommendations for you regarding books, etc. right off the top of my head, but I will do some research and see what I can come up with that may be of some help.

So are all orthodox Catholics, but it helps to realize that the Church has been through periods of change before. I have heard that it takes a while for the effects of a Council to be “shaken out”, so to speak, and so even though there has been heterodoxy, I am actually pleased to see some of the beneficial fruit of Vatican ll beginning to show. I always remind myself: if everything was so fine and dandy before 50 years ago, how come we had the assault on the Church in the Spanish Civil War and in Mexico; the carnage of WWl in Christian countries, and Christian countries like Italy embracing fascism in WWll? Germany was Christian (if rather Protestant), wasn’t it? How come the faith of my parents was so poorly passed on to my generation? Can you lay that ALL on the effects of Vatican ll? I would not let these sorts of things shake your faith: if you believe that Jesus founded the Catholic Church, then you believe that the gates of Hell will not prevail against it. It is our job to understand our faith, and I don’t think that any serious, pious inquiry on your part is going to lead you away from her.

“Many”? Please elaborate.
You wrote: "For example, the idea of Christ’s Church as subsisting inside the Catholic Church seems really foreign idea to me, and I am, admittedly, worried that it may be a change with the intent of furthering ecumenical ends. "
I’m not sure what you mean by “the idea of Christ’s Church as subsisting inside the Catholic Church”—could you please explain? If you are referring to “no salvation outside the Church”, the be aware that the Church Fathers understood “invincible ignorance”, though they may not have used that term. Here’s a short article on the topic:
catholic.com/library/Salvation_Outside_the_Church.a
And a quick quote from that article: "The following quotations from the Church Fathers give the straight story. They show that the early Church held the same position on this as the contemporary Church does—that is, while it is normatively necessary to be a Catholic to be saved (see CCC 846; Vatican II, Lumen Gentium 14), there are exceptions, and it is possible in some circumstances for people to be saved who have not been fully initiated into the Catholic Church (CCC 847).
