I have more honorable kills than someone else. Why does that player have a higher standing than I?
Honorable kills are not the only factor that determines a characters standing. The honor points a character receives from honorable kills are added to other factors, including honor points received for completing objectives in battlegrounds, to determine overall standing.

The new profession in The Burning Crusade is called jewelcrafting. If you intend to level it up, you'll want to match it with mining, as jewelcrafting uses plenty of ore and stone. If you want to switch a high-level character with mining over to jewelcrafting, then you'll have to spend plenty of time searching low-level zones for copper and tin to use to skill yourself up, or buy wow gold on the auction house.

What is the "rating" and how is it calculated?
A character¡¯s rating translates directly into their rank, and how far into that rank they are (ie: a rating of 65,000 means that character is the highest possible rank 14 character). Each character¡¯s rating is calculated by how many honor points they have, compared against all other characters on that realm.
