How much signal do I need to put the MKIII Poseidon board to drive it to full power? The voltage for the stock MKIII is 1.5 volts rms or 2.12 volts peak. Is it the same?

The Poseidons are more sensitive at around 750mV RMS for 60W.

Does the current source make the phase splitter draw 7mA or is that number I calculated wrong?

You are correct - it is nominally 7mA (ref. page 5 of the Nat Semi datasheet).
