You will be using you sword to attack and will likely need a heal charm in your Acc. slot to heal yourself with.
For gear, on HC I prefer welling with an EE armor just because it's safer.
Here is my level 40 set-up and I don't think I have failed a well at that level yet..

The points into Int will give you a larger mana pool and increase your healing power making it able to well pretty effectively.
Warning: MQ welling gear will be extremely expensive to get so be prepared to invest a pretty penny
