It's a fairly vague, broad and open ended questions but I'll try.
Are you accepting user bug reports? You probably want to get access to jira, or GitHub depending on where you are accepting them. If GitHub you may or may not want to change the default assignee for your component.
Are you planning on making code changes? You'll need to get access to the code repo.
Are you planning on making releases? It's possible continuous releases is setup and you can just commit, but most likely you'll need to have access to artifactory so you can cut releases.
