I'd say your default option should be E upgrade first. If you're up against a champion you really need to kite (e.g. an assassin or any melee champion), consider upgrading Q first. Generally, you should only upgrade W last.

As for priority, I'd say upgrade your Hex Core as soon as you get the chance. Not only does it upgrade your abilities, it also gives you amazing stats, so upgrading it will always give you a massive power spike.
