Personally,
from dealing with praise leaders... I would tell you that no book can upfront prepare you for this role. It may help but as a leader, you are the one who must lead the saints in worship. It is your job to set the atmosphere via song.
The most important thing to any successful praise team leader is learning to flow. By flowing i mean, learning that many sundays the spirit will not allow you to sing the songs rehearsed or even in the order you prepared them. Leading worship means, even when you feel a pull in the atmosphere, you should know how to transition into different songs and communicate with your praise team so they can follow your flow.
Moreover, prayer and a good relationship with your team members will get you a long way....that's all i have to offer lol
