2: supply voltage routing

This is a big topic Have a look at our Advanced PCB Layout Course - it is exactly about it: http://www.fedevel.com/academy/onlin...layout-course/

I found one of my older post, maybe this may help you: x86 Motherboard Development Process – Step by Step

Possibly, have a look at this time lapse video of one of our layouts, maybe it will help you too: http://www.fedevel.com/welldoneblog/...routing-video/

PS: Normally I always try to make my answers useful, but this really is a big topic and I would need to write a post about it. Try to search on my Welldone blog, you may find there answers on some of your questions.
