The delay in starting is probably the ECU going "Start with IMA Battery?" --No IMA battery found. "Start with conventional starter?" --Conventional starter found. "Commence starting sequence with conventional starter." --Commencing...
The spark plugs are a DEALER ONLY part. They're labeled A,B,C for each cylinder and are indexed to point the right direction for optimum burn/spark efficiency. ~$9 US each, IIRC.
