The job log and repair. (Divine Divinity)

Good afternoon. Sundry. please explain me two points:
1.How to use the ability to Repair?
I studied it at one point skills. It was the skills and click the RMB (as with any active skill) and on my screen appears the hammer with the anvil. And how can I fix the armor? What exactly and in what sequence should do? And that is the moment that one point of skill gives you the opportunity to repair the item for 60%? Ie, I have a thing with max strength 10, but deteriorated to 1. Does this mean that after the repair strength will rise to 6?

2.How to use the Log tasks? That gives me the filter?
For example, I need to include a letter of response from the guard of some of Sali. I don't remember where she lives. If I like something to choose it (or any other) task in the journal to appear on the map mark where I need to go?
All thankful in advance.
