Surfed a bit through the "cancer fic: brian" tag and found a couple for #1... Ibiza (http://www.livejournal.com/tools/memories.bml?user=buckeye5&keyword=Ibiza&filter=all) by buckeye5 (which I almost thought was #2, but it doesn't quite have all the elements), and a oneshot by devalmom, Watch Over Me (http://delvalmom.livejournal.com/28786.html#cutid1).

I didn't go all the way through the tag, so I'm sure there are more!
