It is possible to do stereo recording? At least, there are unsoldered pin's for stereo microphone on PCB?

Output at Headset and Speaker at the same time

Is it possible to output some audio stream on the headset and in case of an incoming call to (optionally) lower this output, and additionally output the ringtone on the stereo speaker? Or is this not possible due to hardware limits (guess this would require full-duplex output)?

Look at the block diagram for the wolfson codec. It looks like this is not possible. You could eventually do it by using a bluetooth a2dp headset or with some hacking with a bluetooth voice headset.
