For the upgrade to 8.2.15.1, the answers are in the Release Notes Upgrade Section.
Q1: Check the Verify Current CentOS Version item under the upgrade section.
Q2/Q3: You can either provide your login credentials to ASP and let Airwave download the upgrade package; or create an SCP user and use SFTP/SCP to get the package uploaded to your server. More info on the SCP/SFTP user is under Step 3 (Export the backup) in the release notes Upgrade section.
