For LED-AMS, if you booked your ticket on delta.com or klm.com, you will have the KL flight number on your reservation and you will get the mileage. If you booked on an other website and if you have the KL flight number on your ticket, it should be OK.
About your SU flight, you should claim the SM on delta.com and all you need is the e-ticket number.
