That is not the issue. The Rev 12 passage says she cried out from her birth pangs ... that implies she was suffering from the Genesis curse during childbirth. If she was sinless, how could she be cursed with this? ... especially if she was spared physical death (another Genesis curse for sin) by being assumed into heaven.
Not necessarily. It could be symbolic of the sufferings the Holy Family had in the early years of Jesus's life, flight into Egypt and all.

The Catholic Church doesn't explicitly teach whether or not she died at the end of her earthly life. That is a debate that has merits on both sides. Personally, I think she died, as why should she be spared from what her Son suffered? Also, there's the liturgical tradition of the Dormition of the Theotokos in the East.
The passage simply says that she was suffering. It says nothing about any curse applied to her personally. Humans suffer at childbirth and she suffered because she is human.
