Is the transition program TAPS that is currently in place helping soldiers who are retiring or ETSing ?

I believe the ACAP process, while not perfect, is sufficient for what it is. My ETS experience was pretty bad but that had more to do with my local leadership than the ACAP process itself. That being said, I think where we fail soldiers is the moment they leave post for the last time. They just spent years in a rather supportive environment with a group of people with similar experiences. No class about dealing with the civilian world can properly prepare a soldier for post-military life. However, there are plenty of resources back in the civilian world that can help. The disconnect between those two points is, in my opinion, the biggest problem. Putting together localized lists of resources for soldiers when they leave the service, complete with addresses and contact info, would go a long way in helping soldiers make the transition. 

I believe the right classes are in place right now. When I was leaving the Army I took a lot of the same classes that you did and it helped me out a lot. The only one I would like to see added is a classes on applying and looking for the right college to use your GI Bill.
