Yes, you can add extra pages to your passport if you run out of space. Contact your country's passport office or embassy for instructions on how to do so.
No, you cannot add pages to your passport once it is issued. If you run out of space for stamps and visas, you will need to apply for a new passport.
This will usually depend on the places and the mode of transportation that you are to use when you go to travel. As much visa pages the better so that you will not run out of paper when you need your passport stamped.
