I'm used to "3G" and "E" on my AT&T iPhone 3GS, and I understand I may see "4G" on my new iPad when I enter a 4G area.
However, I recently saw "o" on the new Verizon iPad, and had no idea what it meant.
What network connectivity indicators can I expect to see on my iOS devices, and what do they generally mean?
Are the connectivity indicators the same for all iOS devices (with expected carrier differences) or should I assume "3G" on the 1st gen iPad means something different than "3G" on the new iPad?

The "o" means that you're on a 2G network. In Verizon's case, that would be 1xRTT. If you see it on an AT&T device, that means you're on GPRS.
Here's a screenshot from the iPad User Guide detailing what the various signal indicators mean:
"3G" means exactly the same thing on the 1st generation iPad as it does on the 3rd generation iPad. However, if you have AT&T, the 3rd generation iPad reports HSDPA+ as "4G". Since the 1st generation iPad is incapable of using HSDPA+, you will only ever see 3G or below on that device.

On CDMA networks, the °
symbol means that you're connected to a 1xRTT network. You might not be able to receive calls while transferring data over the network. On GSM networks, it means that you're connected to a GPRS network.
