Sketching a graph of a function . . . ?

For the function e^x / (1 + e^x):

A) Find the vertical / horizontal asymptotes
B) Find the intervals of increase / decrease
C) Find the local minimum / maximums
D) Find the intervals of concavity and the inflection points
E) Use a-d to graph the curve.

Now, I don't really need help with E. But any help with the others would be appreciated. I always get confused when it comes to e^x and such.
