Dr. Kent Bradley, the first American flown back from Africa with ebola, is now donating his blood plasma hoping it will do good. He was unable to donate to the man who died because blood types made that impossible. I think I remember this happening before in another outbreak (perhaps as seen on pbs's NOVA). Chances are it won't hurt.

The two new drugs are vaccines rather than treatments for already-infected patients. For the technical minded, the comments on the linked page are detailed and interesting.
