The good thing about this game is that character builds have a lot of flexibility. Your presumably dexterous Ranger can add some lock picking skills and maybe some sneaks while you can compliment with a battlemage or even just a knight or fighter with an added spell capability. Resurrect scrolls and healing potions can serve most of the purpose of a cleric/healer so that leaves you with all your bases covered and free to choose henchmen based solely on role-playing preference. One thing I recommend is to grab the talent early riser for all your characters so when you are resurrected, you come back at full Hp.
