The Shadow Thieves and Bodhi are indeed your only choices in Chapters 2-3. Choose your poison, you've got to side with one of them.
There are at least 5 distinct ways of leaving the Underdark, but to take any of them, you must first visit the Svirfneblin Settlement (what you call "the dwarves stronghold") and talk to their mayor, Odendal Breachgnome. This will start you off on the Main Plot of Chapter 5, which is, in my opinion, the best damn quest in the game: You can roleplay just about anything you want to. Lies, Deception, Honor, Valor, Intrigue, it's all there. It just depends on how you roleplay it.
Just go ahead and play Chapter 5 the way you think your character would play it. And then, should you run into any problems, we'll still be here.
