1: What do you mean by question 1? I don't understand the question.
2: Yes and no. ADS can exchange schematic data using IFF format, and also export netlist information, but the schematic models are usually different between the systems. PCB schematic has no equivalent for all the ADS-specific RF library elements. Depending on schematic complexity, it might be easier to transfer the data manually.
