This is a fairly common build for straight healing in Warzones. This is typically the base, take what liberties you want with it.
Some people like to put points in Concentration (in the Telekinetics tree) because casting Disturbance then improves your Force Regen.
Others like to put points into Egress (in the Seer tree) as it provides more mobility and frees you from roots.
As for the bubble spec, really you just want to make sure you have Preservation (lower cost of Force Armor), and Kinetic Collapse (Force Armor stuns enemies when it ends). The rest is yours to toy with.
