There is a good FAQ for this in the talk.origins FAQ site. (Sorry, I don't have the URL handy)
It is quite an extensive site.
AFA the 2nd law goes, entropy, though the best known value associated with it, is not
always (ever?) the best one to use where life is involved. A value known as the Gibbs
Free Energy is often used inb this context.
In any case, life (nor any other process known) does not violate the 2nd law.
