Just got a cycleops hammer and just wondering what I need to ride it, upgrade, etc.

Ordered a cassette and chain.

I have a ant+ dongle already, do I need a bluegiga dongle for updates or can I do that with my phone? Couldn't seem to find that answer firmly.

Also I have a set of Powertap p1 pedals. Is it better to use those than just the trainer's power curve?

Anything else I should know?
