If a Spirit's Power adds an ongoing effect in a land (e.g., Defend), does that effect go away if the Spirit can no longer meet the Range & Target requirements, or any conditional requirements in the Power?

No, Range and Target requirements are only checked at the start of using a Power, and conditional requirements are checked when you reach that line in the effect text. Once the Power has added the ongoing effect in a specific land, that effect remains until Time Passes.
