Important to keep repeating this. Also - there are no porters at Dutch train stations. Be suspicious of anyone offering to help carry your stuff.
Re cards: as long as your (US) card has a chip, and you have the pin code for that chip, you should be able to pay at the ticket machines and get money from ATM's. I previously used my US debit card (chip plus pin) with no problems all over Europe, incl payment in some (not all, but that might have changed) shops.
