No, you will not have to reinstall all of Ubuntu. I think
all you wanted to do was

chown 700 $HOME

which you don't need to sudo, because you're changing
permissions on a directory that you own.

Yes, your permissions are probably too lax now -- 755 is too
high. It's impossible to guess what the permissions on your
files ought to be, but it's a safe bet that the following
commands will do what you want:

* make directories only viewable by you:
find $HOME -type d -exec chmod 700 '{}' \;

* make regular files only viewable and editable by you:
find $HOME -type f -exec chmod 600 '{}' \;

That should do the trick.
