First off, thanks to Molybdeus for starting this trend with his
guide to Pacal. I hope people will start up a list of guides for Civ leaders and perhaps it will eventually be compiled into the War Academy. I have owned Civ 4 for...jeez, I forget how long now. I really love playing with leaders like Lizzie and Julius Ceasar but for the last month or so I have been playing only with leaders that I am less familiar with. It makes the game more interesting and challenging again. One leader I've been playing with for the last week or so is Justinian.
Spiritual
The spiritual trait allows you to switch civics the moment you gain access to them without falling behind. There are usually some civics that are almost always worth switching to, such as slavery, monarchy, caste system, organized religion, and vassalage.
