41 Super Deluxe Coupe- bring back to life

[TradModelA]

Hello , I just picked up a 41 coupe that's been sitting for a lot of years last tagged in 96. The Engine turns but it is " tight", the brakes go to the floor, etc. What should I do first to bring her back to life? Oil down the plug holes and let it soak, clean gas tank and lines out? About the brakes , a new master cyl and wheel cyl, hoses, etc? Shes a pretty girl and original , I'd like to save her. Thanks guys.
