1.10 Mage Paladin Guide!

I'm going to try out this build now, but I had a quick question.

SKILLS:
Blessed Aim: 5-10
Fist of the Heavens: 15-20
Holy Shock: 10-15
Holy Shield: 1-5

With these skills, which should I go for first? Since all these are ranges, is there one that is more important than the other?

Also, that complete list of skills to get:

SKILLS:
Blessed Hammer: 15
Blessed Aim: 5-10
Concentration: 20
Vigor: 10
Fist of the Heavens: 15-20
Holy Shock: 10-15
Conviction: 2+
Holy Shield: 1-5
Pre-requirements: 15
Salvation: 1 (If you clan to use your Mage for Team Duels)
Meditation: 1

Is that the actual order I should get the skills or is there a certain order I should follow?
