For the playlist answer JT, you can only see what will play next and what is the last 5 song played on the SA main page (
http://www.stellar-attraction.com/)
A list of the entire playlist avaible for us to summon dosen't exist to my knowledge. The closer there is, it's when Darran put on a list of the new album/artist recently added to SA. This situation is different when we have the chance to listen to a session of one of the DJ. At that time, the DJ can put a list of the bands/songs/artists at his own discretion (incomplete or complete).
For the request, you can post a message in the request section of the forum (
here). The next time Progmaster is online, he will gadly queue your asked songs (that is if you are still online).
Personnaly, I wait until ProgMaster is online and send him a personnal message for my request. I don't know if this method is preferable for ProgMaster, so I would advise you to put your request on the forum and wait for an answer from ProgMaster. He will surely answer my question when he is back (I miss him).
Hope this helps!
