That's okay.  Most of them were probably /dev or /sys, or secure files
(e.g. /etc/shadow).  If you want, you can run:

sudo fdupes -nr /

and you'll be able to check more.  Probably not worth it though.

It's not always obvious.  I'll try to give a few tips, as you asked.

This is just a default file.  You should leave it so everything will be
normal if you create another user.

This is apparently a temp file that was copied all over.  You can delete
them all if you don't plan to reinstall.

I would just delete all old torrent files.

Obvious what these are.

Not sure.  What is /home/steven/HOME

Normal.  Just leave it.

These are from old kernels.  Don't try to remove anything manually, but
you can do, e.g.:

sudo apt-get remove linux-image-2.6.25-2-386

Don't actually run that command, it's just an example.  But this shows
how you can remove an old kernel, if you're sure which is old!

Why are you running a CVS server?

You have two versions of Java, which may or may not be what you want.

I don't know.  You didn't post df -Th, and I'm not sure how your
filesystem is laid out.  The command I gave was only an example, as I
said.  It's possible that for instance /etc is mounted inside of Documents.
