Hi wyld
The procedure on how to add vMotion (create VMkernel for vMotion) is described in vSphere Documentation here
HA & DRS is enabled in cluster level so you should create a cluster first (if you haven't) the procedure is available here
vSphere 5.5 Documentation Center - Create a Cluster in the vSphere Web Client
The procedure is also available here: http://featurewalkthrough.vmware.com/vSOM
