Can I upgrade my drives to 2 or 3 TB?

The partition log looks to be like 4 k sector partitions as I see "sectors of 1*512 bytes" in the partition.log. Disk /dev/hde: 500.0 GB, 500097376256 bytes 255 heads, 63 sectors/track, 60800 cylinders, total 976752688 sectors Units = sectors of 1 * 512 = 512 bytes Disk identifier: 0x00000000

Look again at the guide - you need to verify that the start sectors are all divisible by 8.

If your disks are 4k sector aligned the entry for a disk should look something this (you can see the start sectors are divisible by 8, remember 4096 = 8 * 512, so 4k sector aligned disks are also 512-byte sector aligned):

/dev/hdc1 32 4096031 2048000 83 Linux
Partition 1 does not end on cylinder boundary.

Dumb question #1. How do I tell if I have "addons?" I doubt I would as I don't recall doing anything of the sort.

look in services->installed add-ons. ReadyNAS remote will likely be preinstalled, so ignore that one.

Dumb question #2. When backing up the config do I also want to include "Data Volumes - Save the files and folders in the data volumes. This is useful for transferring folder trees and default share contents. It is limited to a combined total of 50MB" as part of the config backup options?

There's no real point - 50 MB is not enough to be useful. So don't bother setting that.
