A: Yes they are
A: Its such a narrow board and so long at 12 feet that it's almost impossible to keep it very straight. If you want something to stay straighter in this type application, you need to choose a much larger piece of lumber, like maybe a 2x6 or 4x4.
A: Not sure your location, but these are typically only available in VERY limited markets. There are 2x2x8 though, in most every market.
