You can buy the paste at electronic stores like RadioShack or bestbuy or even walmart or even better yet order it online.
i guess it all depends on your budget. if you buy it online you will most likely spend about $10.
If you buy a retail boxed processor, yes. You do get a heatsink fan (HSF) with the processor.

Yes, Petco sells tooth paste for animals.

You can buy miso paste to make miso soup at WEGMANS.
If quiet but capable is what you're able, I'd recommend any leading graphics card but with a custom heatsink and fan setup, Look for a large copper heatsink to fit on the GPU and memory of your card, and then buy a 120mm fan seperately. The copper heatsink will efficiently take the heat away from your components and the fan will be big enough so that it will perform well without making too much noise.
Radio Shack or Fry's Electronics
walmart or brook-shires
Drug stores carry it.
I know you can buy beans in a local supermarket
Black market
