Presynaptic terminals indeed contain mitochondria. A paper describing
their significance is "Synaptic mitochondria are critical for
mobilization of reserve pool vesicles at Drosophila neuromuscular
junctions." by P Verstreken et al. (Neuron. 2005 Aug 4;47(3):365-78)

Google "synaptic mitochondria for more"
As to dendrites, there can be mitochondria there, too. See "The
importance of dendritic mitochondria in the morphogenesis and
plasticity of spines and synapses" by Z Li et al. (Cell 2004, vol.
119, no6, pp. 873-887)

As to how the mitochondria get where they are supposed to go, look at
