Van Basten,
1st and 2nd go into the CL (2nd in 2nd qualifying round and 1st into 3rd qualifying round, I believe is the set-up for next seasons CL). Think 3rd and 4th go into the various qualifying rounds of the
Uefa cup.
For relegation, after Dunfermlines win against Hibs yesterday

, means that they are 4 points behind St Mirren with the Saints playing their game in hand against Rangers today. Only 12th in the league go down, and there are no play-offs involving the 11th placed team.
Relegation is far from over now as the bottom 6 play 5 games against each other so St Mirren will need to play Dunfermline again and both will need to perform better in the other games available.
Hope that helps.
