The thermostat goes in the recess of the manifold . The gasket should be glued to the thermostat housing. Silicone sealer makes a metal surface slippery, so if used, should be done sparingly. Let the two adhere and install the housing to the intake. Do not over tighten as a bolt could possibily break. BE SURE THE SURFACE IS CLEAN of the old gasket.
The spring end of the thermostat goes into the engine. If you have the rubber ring gasket, the rubber ring has a slice on the inside of the gasket. Fit the rubber gasket around the outside of the thermostat before you set the thermostat in place. Be sure the thermostat and gasket are in place with the spring end facing the engine and install the thermostat housing, done.
The answer is...it depends. A majority of cars have the gasket going on top of the thermostat. You will have to look for things like a cutout for the thermostat to fit in and such to really know or you might even have to pull out the repair manual.
