Quote #7
Therefore, if you have any home movies, I earnestly advise you to burn them and to be baptized to get born again. (7.12)
Jack is just full of advice. Look at all the transformations he mentions here. Burning home movies is a metaphorical attempt to change the past. Baptism and being "born again" represents religious transformation.
Quote #8
It was like the ice breaking up after a long winter. And the winter had been long. (8.502)
Jack is talking about the tears he shed upon learning that he is the sole beneficiary in the Judge's will. This is probably the only time we see Jack break down and cry. His heart has begun to thaw along with the deep freeze of his past.
Quote #9
I tried to tell her how if you could not accept the past and its burden there was no future, for without one there cannot be the other. (10.432)
Jack's feelings toward his mother have transformed considerably from the first time we see them together. He's trying to explain his larger transformation to her as she prepares to embark on what we hope will be transformative for her – a trip to Reno.
