It is possible to do it; in the partition manager during the install process, choose a manual partition setup. Then set your home partition to the /home mount point and untick the format option, but let it format the other partitions.

Just one snag: Make sure your UID and GID are the default 1000 settings which is what Ubuntu will make your newly created account when you install, otherwise you won't be able to access your home directory and its contents.

The config files are just plain text, so they're exactly the same for 32-bit and 64-bit.

Regarding UIDs, if you set up your users in exactly the same order, they'll end up right. Otherwise take note of the current settings and make sure you set them that way when you set the users up on the new system. Even if you do muck it up, just issue this command to have the user take full ownership of their home folder:

sudo chown -R username /home/username

I done this many times with my /home on it's own partition. As mentioned above choose manual to edit the partition to set the mount points. The format box is default set to not format. Just dont tick it for the /home partition but do tick it for /.
I just reinstalled this morning as opensuse 11, installed to second hard drive, ate grub and gave error 15 which supergrub could not fix.
