I do to maximise these 2 things

But what I really want to do is get ready for raiding, and be ready for raiding when or soon after MSV goes live. http://www.euwowgold.fr/ I can see that I need to be revered reputation with various factions in order to be able to get epics, and I also need valor points. So, what can I do to maximise these 2 things?
