The audio out is a fixed value, but once you get the sound card gain 
set, it works well. I use the RF gain as band conditions warrant. Your 
current setup is all you need for RX.

I use a very simple interface, straight thru on the RX and a voltage 
divider on the TX. Google psk31 interfaces and look around. I will say 
there are some very expensive interfaces that are just overpriced for 
all there is to them. I prefer to keep it simple. If you plan on using 
RTTY then you will want to use the FSK keying. For FSK a 1k series 
resistor and a connection to the TXD pin in the serial port is all that 
is needed. It will require you to unplug the PTT line from your psk 
interface tho.
