You dont have any redundant links on the network so on a basic idea, you can get away with the STP root part of it. But I would suggest you to setup the DS switch as the root bridge for all the switch/vlans running on the switch. This way you have a control on the L2 traffic across your network.
Imagine a situation that if dont have control over the L2 root and if someone introduces a switch or a redundant link between the switches, this might bring the entire network on a halt and will have adverse effect on your network.
I would suggest to have a manual control for the root bridge placement on your network.
You dont need to configure the core as the root brodge as you are running a L3 link between core and the DS switch.
