God Bless
Well i play percussion at my local church, so i hope i could help you. The percussion play gives flavor (spanish-flavor) to the music, it keeps the rythim and adds rythimc tones to the music. A percussion play sould never play what the drummer is play, he or she should not interupt the drummer from any fills the drummer is doing. The percussion is filling the music up, so it does not sound empty.
The first thing to set up the percussion side, is to get congas(with high stand) i recommend Lp Classic congas

(which is the one i use). Buy the mini Lp (tito puente) timbales, this will be good for latin rythms and also after a drummers chops. Get a percussion table, and supply the percussionist with tamborines, shakers, triangles, jam blocks, cow bells, maracas, etc. vist
