Adding to all the above, make sure I've an accessible but secure location to store my library of SQL scripts (every DBA should have one) and get them onto the system ready for use.

Then create server specific (and for the main databases, database specific) backup and restore scripts with the right drives for backup files, data and transaction logs - it saves time and blushes when you have to do one in a rush and forget that the data goes on K not D on this particular server and that there are twenty orphaned users to reconnect!
