You really need to be more specific if you want helpful answers. Look thru the trip report forum for some fantastic write-ups on RTWs. Look at all the thread titles in this forum for the past several months. We've written lots - before, during and after trips. You'll find all kinds of information, including many many routings that various of us have taken. You'll also find a wealth of information on the service in first from the various carriers.

I don't mean at all to be rude in this comment, but think on this analogy - you're asking what is basically a first grade question of people who hold graduate degrees in RTWs. We're delighted to share our knowledge, but you'll want to move up the learning curve first, based on all the information readily available.
