Will this phone work with a PoE switch or do I have to use the included power?

The SPA 300 series phones do not have PoE support, so you would need to use the included power adapter. The SPA 500 series phones do have PoE support, so you may want to take a look at them if you need PoE support.

Will this work from my internet alone, or will it require additional hardware?

You need an internet connection and phone hardware.
