Mathematica How do you plot a 3D vector in Mathematica 8?

[globular]

For example, how would I plot the fixed vector <3, 4, 3>?

I'm not sure if I'm using the correct language; I mean the vector with its tail at (0, 0, 0) and head at (3, 4, 3).Also, how would I plot the plane 11x + 19y + 39z = 88?
