What are the consequences for turning down a mission?

If you turn down two or more missions within 4 hours, you will suffer a small standings loss. Note that the standing loss for declining a mission is smaller than the one for failing a mission.
A better alternative is to find an agent from a division that only gives you the kind of missions you want. If you for instance only want Kill type missions you want to find an agent from Security, Internal Security, Command or Surveillance.
You can see what type of missions the various divisions will give you here: http://www.eve-wiki.net/index.php?title=Agents#Mission_Distributions
