I think I understand all the other chemistry components of the water with a SWG, but I am not sure I understand the CH component. Everything I read says that CH and vinyl are not even an issue. Then the recommendations for the SWG is minimum CH of 150. My current CH level is 110. Do I need to bring it up?

No, probably not. Low CH levels can sometimes cause foaming. There was a debate a while back about how frequently that is actually a problem. If you have foaming problems that last for more than a week or two, you should raise your CH to at least 150. For most people, CH can be very low without problems in a vinyl pool. I would leave your CH low unless foaming becomes an issue.
