1. A voltage gain of 20dB is equivalent to 10x the voltage. This means that with full 2v input, the amp will try to put out 20v. Into an 8ohm load, that means 2.5 amps or 50watts.
2. As for a passive, which seems preferable since CDs do vary in their levels and running direct cannot let you compensate, that depends on the output impedance of the transport and the input impedance of the amp. What are they?
