The game provides a reasonably good structure, but in the first game the Bhaalspawn stuff doesn't really become relevant until very late in the game. I'd strongly recommend starting it out as a generic party meeting up in the Friendly Arm Inn and being hired to investigate the Nashkel mines.
That way you let the players bond as a party instead of being "the hero" and his companions, and you can always introduce the Bhaalspawn angle later, once they reach the city.

I remember wiping repeatedly on the stupid pitfiend that you digged out in the underark. After everything else failed I tried the slayer button and watched stupefied how my main char turned slayer single-handedly tore the pit fiend to shreds as if he were a lowly koboldPretty sure you don't go full bhaalspawn til BG2 though, which in a few encounters was the only way I was able to win.
