Hi Iris, I'm gonna try to help you in more detail. As Alejandro said "dar bombo" means to hype or to promote or publicize (a product or idea) intensively, often exaggerating its importance or benefits. About the expression "la vez está dada" I don't really know, I should know the context first. But in Spain we ask "¿quien da la vez?" when we just come to a line or row (for instance, in a store or bank), and we ask that to know who is the last person on the line. Hope this clarifies your doubts.

En México La expresión Dar bombo. Significa hacer elogio con exageración. Ejemplo: Dar bombo a la presentación del libro (lo que quiere decir es que se dijeron cosas muy buenas del libro). La expresión "la vez está dada" no la he escuchado. Ignoro que signifique. In México The expression “Dar bombo” means to do eulogy with exaggeration. I do not know is the expression “la vez está dada"

those are very probably expressions used in some specific country. My native language is spanish and I have no idea, what that could mean :)
