How can I clean the smell of cigarette smoke from my camera body?

I followed other's suggestions (wipedown, etc.). Additionally, I put it in a box with a small container of baking soda for a couple of days. Seemed to do the trick.

Why isn't my DSLR's viewfinder showing focus correctly after removing it for cleaning?

Solved. I accidentally placed the focusing screen by flipping it on other side which made in focus objects blurry. I corrected it and it's back to normal now.

Can dirt on a camera's lens cause graininess, without causing large-scale blurring of the picture as a whole?

Yes, it's possible — but it's more likely that that's just how it is. You can't expect miracles from a point and shoot camera, and fine detail with no noise when "pixel peeping" would be a miracle. ...

Does the size of blower matter to clean the sensor of the camera?

Generally speaking, I think the size of the blower has more to do with its portability than anything else. :) Most folks get a larger one for home use, and a smaller one to carry around in the bag or ...
