I have 2 different printers who take my high res pdfs. They each supplied me with a PPD specific to their workflow for me to use when making the pdfs. I set up a test file & emailed it to them. They ripped it & everything worked perfectly. Now that InDesign generates pdf/X-1a pdfs, this alone might work just fine.
It's always best to talk to your printer before you get too far into a project. Let them know what you are doing & ask them what they need. Some printers like a pdf for each page, mine prefer a single pdf for all the pages.
Most printers are more than happy to help you solve any issues long before they become problems at the press stage. Most of them are willing to rip a test file to make sure everything is working with their particular workflow.
