Sorry but i cant help on most of these questions. Never seen an airsoft cutts compensator, a real one may fit as the real safety catch and fire select fit and fortunatly these are legal parts you can buy and have on occasion come up on ebay.
never put real wood furniture on so cant help there
Blued finish, again not easy, i have only ever used a zinc black which is the same as original colour. blueing gel or liquid is not expensive so you could try that.
take down tools, never seen any and never got any with mine.
Not really helpfull i know, sorry about that.
