Reddit mentions of Agile Project Management with Scrum (Developer Best Practices)

There's this, that has a couple 'real world' examples

I don't think I'd start with a certification class. I'd start with two books:

• Agile Project Development with Scrum
  
• Kanban
  
  I'd also look at some other online resources (like this agile roadmap to get a sense of what you actually want to implement and change.
  
  From there, that will guide you to what classes, or as /u/mlucero14 pointed out, if you'd prefer to bring in a coach or trainer.
  
  Given that it looks like you all are in Costa Rica, you might want to talk to the team from Pernix Solutions. I've worked with them before, and they understand the agile and craftsmanship side of things.
  
  Hope that helps!

Good list!

Does it make sense to add a 'methodology' category for the SDLC. I think it's important that software engineers understand good PM/Agile principles.

Not sure the best book but books I like the 'Agile Manifesto', or Alistar Cockburn 'Crystal Clear' (http://www.amazon.com/exec/obidos/tg/detail/-/0201699478/ref=ase_alistaircockburn/102-9370806-2432911?v=glance&s=books)

or a Microsoft SCRUM book.

and the Mythical Man Month:

To me books like these and the feedback loops it teaches will help deliver software that somebody 'wants'..
