(for the initial question!!)
well i'm not at a high enough standard of physics yet to answer your question but i have read a great book about the formular E=mC^2:
E=mc^2, written by David Bodains, published by walker.
the first few chapters after introduction to einstein bit are devoted entirely to the formular it explains each symbol in depth, i'd recomend it to anyone as it is not very technical.
can i just say note that the speed of light is squared this makes the number huge
something like 9x10^16m/s. and i do know there was a special reason for this but i can't remember what!!!! sorry
