For home files, try du -kSx /home | sort -nr | less to find large directories, and find /home -type f -ls | sort -nr +4 | less for individual large files.
To find large packages, try
rpm -q --queryformat '%{SIZE} %{N} %{V} %{R} %{SUMMARY}\n' -a | sort -nr | less
and remove the ones you don't need.Toby
