Cable help for NEWBIE

Hi all: I have a Marantz SR8000 Receiver (DD/DTS-24 bit/96kHz)@105WPC, and just purchased a Denon DVM 3700(used)DVD/CD changer that suports these features. At present, the setup will be a 2 channel system (Maggie MMG'S as fronts). My question: what cabling will I need? Additionally, the back of the Denon DVD has two(2) slots: 1.Coaxial and 2.Optical, however even though I have the manual for both Units, I sadly can't quite comprehend how these 2 outputs comes into play.I was hoping that you kind experts could help.
