This thread started with you having trouble getting mercenaries to follow you. If you've figured that out, and if you're just having trouble getting the bow, then you should use the search feature to find other threads on the topic. Skorm's Bow has been discussed to death here.
But here's a hint: the more evil you are, the more trouble you're going to have getting the bow.
Edit: You might also try looking at our walkthrough
