I have read alot of posts that suggest inserting a Doombull into a unit of Bestigors. The problem that I run into is that I am really not sure how to properly rank up the unit as the Doombulls base is 1.5 the length of the Bestigor bases (it makes it pretty akward). Does anyone have some kind of a diagram that would explain how to properly do this? Secondly, would I need 3 bestigors + doombull to have a unit wide enough for a rank bonus, or would i need 4 bestigors + doombull?

This question is answered in the 2nd FAQ of the main rulebook. You can find it here. Look on pages 3-4.
