Can my HomePod connect to my apple phone using bluetooth?

No. Bluetooth is required during setup and handoff, but music playback is AirPlay over Wi-Fi. HomePod is not a conventional Bluetooth speaker.

Yes. Siri on HomePod is able to access your unhidden purchase history, or your iCloud Music Library if you have a subscription to Apple Music or iTunes Match. You can also AirPlay from your computer or iOS devices.
