Answer 1

1. What change do I need to make while importing since database version in source and target are different?You don't have to do anything. You are exporting metadata that will be recreated in your new database and new version. Just run the import command.
2. Do I need to change any thing in my import command?I don't think you need to change anything. You an add parallel if you want, but the import parallel does not have to match the export parallel, so keeping it as you have it will be fine.
