I had always problems to understand the behavior of "Set value" :-S Maybe because we have the abstract term "Value" here... What about:
Resources tool:
Label 1: "Increase/Decrease amount by:"
Tooltip 1: ok, already uses the term "amount"
Label 2: "Set amount to:"
Tooltip 2: Just add a sentence: "CTRL + Click on the map to set the amount of selected resources. This replaces already set resources."
Height tool:
Label 1: "Increase/Decrease the Height by:"
Tooltip 1: already ok
Label 2: "Set Height to:"
Tooltip 2: ok
