Yes, that is a very good idea. I have a separate partition for /home, and *always* do (full) re-installs rather than upgrades. Works fine with single step upgrades, don't know about skipping 2.
I also have two separate partitions (other than /home) so I can flip-flop releases, and fall back in need.
Edit: forgot to mention; on the re-install, specify your partition as /home and don't format it as part of the install. Ubuntu will offer to carry across your userid(s) - use the same password(s).
