Usually you would not, if you are talking about parks in general. If you are not talking about a specific park, then the state parks in Washington would be referred to as the Washington state parks. Say that there is such a thing as the Washington state Parks Commission (I have no idea; I just made it up) Then you would refer to this commission as the Washington State Parks Commission.
If it is the word 'state' you capitalize the first 's' like this 'State'.
Capitalize the word state only when it appears after a state's name, as in "We will travel to Washington State this summer." (But make sure it won't be confused with a visit to the university known as Washington State. Perhaps "state of Washington" would be better.) In the phrase "state of Hawaii," you don't capitalize the word state. Finally, don't capitalize the word state when it's being used as a substitute for the state's name, as in "My father works for the state." It is capitalized, however, in imaginative names such as "the Nutmeg State," "the Empire State," "the Aloha State," and we capitalize "States" when we say things like "We're returning to the States after twenty years in Europe."

Not unless it is part of a proper name. The expression "Washington state" is used to indicate the state instead of the city (Washington DC). It would be capitalized if "Washington State" meant "Washington State University."

Yes. It should be Peachy State.
washington is called the evergreen state because of its numerous and many trees and national parks today , still living ( trees)
You capitalize the "s" for state when you referring to a specific state or state agency; State of Texas or State of Maine or The State Dept. of Health. You don't capitalize the "s" when the word state is used in general terms; the states with the largest population or the western most state.
When it is used as a name of the theater, then it should be capitalized.
Yes, "State" should be capitalized in "State law" when referring to laws specific to a particular state within a country.
