That's pretty much it, but you probably want to use the non-mapper devs of
/dev/vg1/home  I'm not sure how the LVM tools would like the raw device.
It'll probably work, as the entries in /dev/vg1 are links off to
/dev/mapper, but it never hurts.

Also, you didn't mention the distribution or kernel you're on, but if its a
new enough kernel and new enough e2fsprogs, you can do the resizing without
unmounting the filesystem.
