BOSS sorts automatically, and also provides a log file with usual content--such as noting when you have an out-of-date ESP that can be replaced, or some potential ESP conflicts. You can take action on these or not; it's your choice. But again, the sorting of your load order is done by BOSS.
Don't worry for now about cleaning your files with TES4Edit, or Wrye Bash. Just get up and running. Plenty of time once you've played for a bit to consider other matters.

Thank you. I have just opened the game and it's running okay, so that's a good thing. hehehe. I'll try and learn more about the cleaning program, as it does look productive.
