You might also want to expand upon the tires part - the tread on all four tires needs to be within 1/32" to 2/32" of each other and they all need to be the exact same size, brand, and style so you don't risk damaging the differentials. If you have a flat tire and it's damaged beyond repair, you'll have to buy four brand new tires which will set you back several hundred dollars. That chunk of money should also be included in your "oh crap" or possibly "routine maintenance" fund.
