as a non tobacco user myself, i can try to give you an unbiased opinion about the mixture of weed and tobacco in your hookah...aw hell, just dont use the hookah. get a real glass bong, or borrow one, to use while introducing your friends to bud. bongs are by far the best smoking method ever. id go with that if i was you. eating the weed might be too intense for teh first tiem, and they might not get high.
