Adding extra insulation to your spa will depend on your spa. Some spas come from the factory filled solid with insulating foam while others have fiberglass batts stuffed into the cabinet and some have nothing.

One of the easiest things to do is get a good cover. You can search online for an aftermarket supplier. They also come in varying thicknesses so you can get the amount of insulation you want. While you are at it, a cover lift is worth every penny. They can make it really easy to handle those large covers.

I'm not sure there is much you can do to insulate the spas vibration from your house. The spa is very heavy so setting the spa on a rubber mat probably will not do much. Having a good sturdy base/foundation for the spa will be the best thing for limiting vibration and noise. A weak, shaky deck will make vibrations more noticable.

Adding insulation may not be necessary. Depends on what is under there now. After about 4" of 2# foam the law of diminishing returns takes over.
A new cover, or like new is an excellent pace to start for economy.

For the pump, you can get semi-hard foam rubber, (neoprene) that will act as a dampener this can be placed under the whole spa or under the pump and pack, for added acoustic insulation.
