Have a look through https://confluence.atlassian.com/adminjiraserver073/upgrading-jira-applications-861253088.html - that will lead you through the upgrade process.

To give an immediate answer:

1.  The home directory, the install directory and you'll need a copy of the database.  Which bits you use depend on what you're planning to use the backup 4.

2. See 1.

3. Follow the upgrade path in the doc I linked to, it's an essay question, but not one we need to repeat.
