Yes, I have studied the documents, extensively, both in graduate school and since. There is no question that the overall thrust is for reform. Otherwise, there would have been no point to them.

What you're doing with these quotes is similar to what some do with Biblical passages, which is to take them out of context to try to prove a point that, in context, isn't there. For example, your citation from Sacrosanctum Concilium about singing responses in Latin completely disregards the statements immediately before and after it on celebrating in the vernacular. 

The larger point is that the Vatican II documents made no claim to be the final word. But they did, clearly, set forth a viable structure for making thoughtful, deliberate change going forward. You don't seem to care for much of that change, and I respect that. But cherry-picking passages from the documents isn't a particularly effective way to argue against it.
