Method for building FAQs section using blog posts?

I would like to construct a Frequently Asked Questions section for our site, and it seems like a workable method would be to devote 1 post to each Question/Answer pair. I would start by doing one post for each Q/A pair we already have (about a dozen), and then just add new posts as future questions come in and get answered.

I’m thinking that would allow better searching of the content overall, and that a good layout arrangement would limit the number of posts displayed per page to 5 maximum.

Does this idea make sense? And, if so, where do I specify the limit on posts per page, and how would I automatically add a breadcrumb function at the bottom of the page to direct readers onward to additional pages?

Thank you.
