New member with new house

I've bought a house that is 30 years old. Before I move in, I have to update and upgrade it, including new floors, painting the walls, new appliances, kitchen, bathrooms and maybe enclosing the screened porch. I'm not sure where to get started with this. Or example, I'm planning to have wood laminate installed throughout the house (except the bathroom). What do you do first, paint the house or install the floor?
