cooking basics - hard to reach smoking temperature

Hi,just fired up a "bbq-pro" charcoal grill with offset smoker box model cooker. It was hard to get heat past 150 until we added wood to the brickettes and then only 200. It was cooking for like 1.5 hrs. We started late so transfered over to gas grill to finish. Basically we should be cooking at what temp.?
Second,chicken and sausage was pinkish color and family thought it wasn't cooked enough. Is the color of the meat look different when smoked?

thanks,Dennis
