If you have World Edit you can do /remove <type> <radius> (eg. /remove drops 11 ,OR, /remove amates 11, etc) command when you log in but if you log in and crash before you can write anything try make you render distance vey small so you dont see and than do the command. if that doesnt work than Download "MCEdit," open your map in MCEdit, then remove the dropped Items.
