As a Certified Financial Planner, I'm authorized to give planning advice for Canadians, but not outside Canada.

Having said that, I think I may be able to give you some food for thought.

It's a huge amount of materials, ... I'm quite sure you'll not do more than skim it, so here are some short&direct answers to your question:
