Volume? It's the first Fader on the right (Master output)

Yes, you can use FX on your audio stream, but you have to use Jack as audio
driver. Hydrogen has up to 32 jack output ports: you can assign every
instrument with a different FX (e.g: with jack-rack)

Again, JACK is the solution. Hydrogen is a jack-transport enabled app, so you
can share the bpm and the song position with others jack-enabled programs.
