I've only ever made partitions larger by allocating
previously-unallocated space, and I've only ever done it on reiserfs
filesystems, but the steps you suggest look logical to me.  I think
resizing resierfs volumes can be done without unmounting first, but I
don't know if that applies to ext3 volumes.
