Gparted has a nice feature where when you do something like
delete a partition, it does not do this immediately. Instead
it waits until you apply your changes. Now on Mint, the
apply occurs as a button on the button bar at the top. In
Mint that is a check mark.

See above.

update-grub just gathers the current information. Since
Ubuntu will be gone, it will build a grub menu with only
Xubuntu on it. However, it does not install it on the
disk until you tell it to. This is done through grub-install.
I missed one thing. It should be:

sudo grub-install /dev/sda

This is assuming your boot drive is a SATA drive and it
is the first drive in the system. If your boot drive is
PATA (IDE) then it would be

sudo grub-install /dev/hda

You can figure this out using the following method when
in Xubuntu. From the command line type:

df -h

This will give you a list of all partitions currently mounted.
There should be one mounted to /. This is the partition on
which Xubuntu is loaded. Remove the final number and you
get the proper disk on which to install grub. For example
here is mine:

$ df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda3 39G 5.8G 31G 16% /
udev 3.9G 4.0K 3.9G 1% /dev
tmpfs 1.6G 1.1M 1.6G 1% /run
none 5.0M 0 5.0M 0% /run/lock
none 3.9G 1.1M 3.9G 1% /run/shm
none 100M 12K 100M 1% /run/user
/dev/sda4 39G 7.9G 29G 22% /alt_boot
/dev/sda5 834G 517G 275G 66% /data
//10.100.1.202/OracleRetail$ 40G 16G 24G 40% /data/alsshare

Notice that / is /dev/sda3. Removing the number, the proper disk
on which to install grub is /dev/sda.

It will work, however, the way I have it set up is that data is
a separte partition. That means when I install a new OS on the
system, I just have to add that partition to the new OS as
/data WITHOUT FORMATTING and all of my data files are there
without having to restore from backup to see my documents.

That is certainly commendable and you should do that.
