The MFJ 9020 is an exellent piece of equipment and the audio filter it's sitting on is the Howes outboard filter, I can also reccomend this as a good first kit.
Headphones are by Tandy, their cheap mono lightweight phones and the key is one of about 30 I own, I use whatever key takes my fancy at the time!
