The basic essentials for living in a car are a blanket, a pillow, and a mattress or some other padding. Due to the angles involved in the seating setup, you may develop dull back pain from the cramped quarters. Should this happen, be sure to have pain medication on hand. Once you have your sleeping gear, you'll want a blanket to place over the back seat, and draped over the two front seats. This will block light and people's views.  A cheap cooler will help make life easier. The main thing the cooler needs is to be waterproof. Cold food will cause condensation, while ice will melt. You don't want that water inside of your car. A cooler will help keep your perishable food cool. It will work most efficiently when full, so add bottles of cold water to it as you take out food. If you choose to buy an electric cooler, it will need good ventilation to work. For this reason, it will not work well in your car's boot. It is best placed within the car when running. Make sure it is only running when the engine runs, or use a low voltage cut out device, as explained below. Make sure the cooling vent grille is not touching anything as it exhausts waste heat and may set some things on fire. One essential item, if you can afford it is a Porta-Potty, a chemical toilet. These devices can really make living in a car bearable. They can be purchased for under $100 new these days. If you can't afford a Porta-Potty or don't have room for one, you can pee into wide necked bottles like Gatorade bottles, or make an improvised bucket style toilet. Have a spare tire and at least one can of tire sealant. Be sure the sealant is of the type that can be removed. A cigarette lighter converter is one option. These are useful for powering low consuming devices (100 watts), but if you plan on using your vehicle for cooking, then you'll need to draw power more directly from your battery or you'll blow the fuse. Running electric cooking appliances from your car though is fairly impractical without an expensive dual battery and inverter system. There are small 12 volt water heaters and skillets, but these generally are not very efficient. You will also need a much more expensive inverter if you plan to run things that use mains voltage. You may need to idle the vehicle while drawing this power if you don't have a dual battery system, however even then, car alternators are not designed for such use and may not be able to produce the current you need.  A good buy for any car dweller is a low voltage cut out device. This device protects your car's battery by cutting off the electricity once the battery reaches a voltage where it can still start the car, but can't really run plug in devices much more. These usually retail for about $25-$40. They are  a very good investment for a car dweller, as continual flattening of your battery will damage it, resulting in a costly replacement, and inconvenience of not being able to start the car. An alternative to electric cooking devices is to use gas for cooking, but do not use this inside the vehicle for safety reasons. There are many dangers associated with cooking inside your car: unstable surfaces, fire hazards, burns from hot metal or spilled liquids, carbon monoxide build up, smells. Cooking is for outside of the car. If you live in a van with a stable set up for cooking, then cooking inside is okay, provided there is ventilation. Get bags you can fill with your soaps, clothes, cell phone, etc. Keeping things in order will save you a lot of hassle. A vehicle may seem like a small space, but losing things can be extremely easy. Also, keeping things neat inside the car will draw less attention from people passing by who happen to look in the windows. Hiding your bedding might be a good idea (consider the trunk).  If there is not room in the car for a weeks worth of clothes and supplies, try to leave them at a friends for safekeeping and then you can have a reason to come over, and they may give you a shower and a place to hang out.  When you do your laundry, be sure to get them bone dry, as you do not want damp clothes to mildew or smell bad in the car.  When you're not in the car, leave windows cracked and dryer sheets scattered about to keep the interior smelling decent. Wash your sheets once a month, or else you risk smelling like a homeless person, which will blow your cover and get you treated like a homeless person.  A 3 or 4 battery Maglite flashlight serves two purposes: lighting and security. It is large enough to act as a metal baton to defend yourself, should the need arise.
