Check the following locations for apps that automatically launch on startup and delete any you don't need/want:

• System Preferences > Accounts > yourusername > Login Items
  (Lion and ML users: System Preferences > Users & Groups > yourusername > Login Items)
  
  
• /Library/LaunchAgents/
  (Lion and ML users: In Finder, click Go > Go to Folder > then enter the path above)
  
  
• ~/Library/LaunchAgents/
  (Lion and ML users: In Finder, click Go > Go to Folder > then enter the path above)
  
  
• /Library/StartupItems/
  (Lion and ML users: In Finder, click Go > Go to Folder > then enter the path above)
