Just one comment on this high-quality list, for podcasting.

Google seems to have basically abandoned 'google listen'. After trying various programs, I've settled on BeyondPod. While it takes a while to configure and has some rough edges, it will automatically download new episodes and delete old ones.

It lets you set to only download when the phone is on wi-fi, or charging, or both (my personal preference).

I wish Google had at least released the sources for Listen. I like it far better than the three or four podcast apps (including BeyondPod), but it needs maintenance.

doggcatcher is the app I use for podcasting. It is highly configurable, can do all the things you mention and a lot more, and isn't rough around the edges at all.
