Will this work with Vonage?

No. Vonage ships this unit to their customers with custom firmware on it.

I have a skype account and telephone number, will this support calls in and out with the old analog phones?

I don't know if Skype offers a VOIP service. This device is a supported device for Vonage VOIP service connecting to an analog phone. I've only used Skype on a computer with a camera and microphone.

Does this require a wired connection to the network or does it support a wireless connection too?

No wireless support, you need a physical ethernet cable.

Can i power this from a 12v dc battery by running a cable directly from a usb port that the battery powers to the micro-usb socket on this device?

You could use a car-type 12v to 5v usb adapter. Not 12v directly.
