Regarding Default Partition Resizing

Yes, this AMI is configured with LVM. Meaning scaling and resizing the partition is different than just using the resize2fs command. However, this can be learned:

https://www.centos.org/docs/5/html/Cluster_Logical_Volume_Manager/index.html

You have to learn how LVM works to learn how to resize it.
However, there does seem to be great advantage in this as you can keep adding volumes and expanding the LVMs as desired with the same logical volume. Seems very scale-able.

Good luck!
BTW, this may be the best CentOS 6 image for my needs, so learning it was necessary.

As for Additional IP addressing on the same Network Interface this greatly helped me out:
