Yes, it is talking, and yes, it looks pretty similar; dark colored fur and a bit of a malevolent intelligence in its eyes.
After you deny its request, you can see them lowering their stance to attack, so you take your attack on the first worg -> d20+10 = 14. You hit for 1d10+7 = 10. The worg is still up, but the two cuts are fairly deep.
Your guys horses (predictably) take off. Worg 1 makes an attack of opportunity on the horse -> d20+7 = 24, and hits for 1d6+4 = 7. The horse falls to the ground!
Worgs 2 and 3 give chase after your horse. Right now, they're all moving at the same speed (50), so the horse has the lead.
Round 2
Worg 1 retreats (100') as a full-round action, to avoid and attack of opportunity.
Right now, they're all about 100 feet away.
Sorsha draws her bow and shoots the injured one -> d20+5 = 24, and hits for 1d8+3 = 10, which staggers the worg. It stops running.
Gregor is up!
