I suppose I haven't studied all the canons of that Council "enough" :) to know if I agree with all of them or not. (Actually, I could only find summaries of the Council, but not a list of the Canons.) At any rate, I don't see any problems with Canon II.
Now, it seems pretty clear that those who deny the perpetual virginity of the Most Holy Theotokos are anthemized by The Church and have been since the 500s.
In Canon VI, unless it is included in one of the references I wasn't familiar with, it looked like Mary's perpetual virginity was sort of mentioned only in passing. It looked to me like the meat of the Canon was fine. However, if even that one part would constitute disagreeing with the Canon, then I suppose I would. If Mary was not a deity herself, then I guess I don't understand how she is diminished by the idea that she was a loving wife to her husband and a loving mother to other children.
Do you think Christ would have lived no less of a consecrated life had He married and had children?

"Other" children? No doubt you have Scriptural proof that they were Mary's children, right? And please don't bring up Jesus' "brothers" and "sisters" we have been through that already on this thread several times.
As to being a loving wife, Consider what St. Gregory Palamas says:
If God were physicially present in your home, would you tend to other interests? Would you put God on a "backburner?" Would you, in His presence, find other things more interesting? (please say "No!")
