Welcome from Chicago! It looks like you are on the right track, fresh fluids and fuel is the best first step to starting something that has been sitting that long. I would also prime the engine oil after you fill with fresh oil. Also, like Sheriff mentioned look for any rodent damage to the harness and get that repaired if you can before you hook a fresh battery to the system. You always want to avoid installing the new battery and smelling smoke if you can. Also I am a fan of changing out brake rubber hoses when you flush out the brake lines and adding new fluid. The hoses close up internally with age and fluid sitting in them in storage, this will restrict flow and often make that area of the brake system not functional. You can drain the lines and removes the hoses and clean out steel lines with brake clean and a little air pressure. After that, install the new rubber hoses and add fresh brake fluid and bleed. Good luck getting her back on the road she looks like she will have plenty of giddy-up, enjoy!
