My suggestion about the planting forests issue, if it is not to complicated to impliment that is, would be to have the forest harvesting shield bonus to only apply to one construction project at a time.
example: you are building a temple and you have your workers out clearing the forest, and once their task is complete and the 10 shields are returned to the temple building city, they could replant the forest and start chopping it again. the city would only recieve the 10 shield bonus if it had completed the temple and had been switched to a different project (other than Great Wonders, etc. etc.)
