please suggest a plugin solution: workflow after post is published

I would like to do some SEO workflow after a post has already been published. I would like simple checkboxes on the Posts list that I can define and saved. Or a private todo list per page / post. Not to be published todo list but for myself. Where I can check off things that I do per post / page as I finish things off. ie directory submission, bookmark submission, ping,

Are there any plugins already like this here or in the wordpress repository?
