Commercial use of some data and texture

Hello,

I have a few questions.

I am writing a book, the book will be sold in many countries in many different languages, and I need to make 3D terrain of part of Jerusalem, and if I want to do this terrain I will need data for height points for this area of Jerusalem and I also need terrain texture. And my question is: Can I use data from openstreetmap, and can I use texture of that area also from openstreetmap (print screen method). I am also interested if you can tell me how I can turn off street names and some icons from the map so that when I will press print screen those names will not be on the picture (I want texture without names - I only need roads, hills, but not names etc.) Can you help me, please.

You can also export small areas from the main OSM site as PDF or SVG and delete unused details via inkscape or Adobe Illustrator
