Have them input your card number when you check in at the counter. You might not get any miles if your fare booking class is not applicable for miles. However, both J (130%) and C (125%) in Business will award you miles.
Skyteam does not have a FFP, it's an alliance. You follow the FFP of the program you decide to join. You can be Delta's FFP and credit CI flights to DL FFP for DL miles if the fare code is applicable for miles under DL FFP. When you redeem for awards, you can redeem them via the FFP that you have chosen.
You will be entitled lounge access for CI flights at Amsterdam and Bangkok. I have no idea about EI flights. You already bought the ticket so you can tell yourself after trying out the flight. Basically, you get what you pay for (which is not expensive compare to other airline's Business Class).
