1. I cut around the anus and remove it that way. I do not split the pelvis, as it exposes the hams, causing meat to dry out and have to be trimmed off later.

2. I do not split the sternum either. There's no reason to do it.

3. Personaly, if it pumps, thinks, or filters, I don't eat it. Others do. It's up to you.
