I got this question a while ago: how do you set up a document so that the page numbers go 1, 3, 5, etc.?
You take advantage of something that some people find to be a problem but can actually be used as a simple solution for exactly this situation.
In books, the first page, page 1, is on the right; you get page 2 when you flip and start reading on the left side of the spine, and so on. Writer is set up like this. 
If you have a right page, then you instead of doing normal flow have another right page, that skips the left page so you go 1 (no 2 from the left), 3, and so on.
Video tutorial, take 2. Smaller display area. It takes a while to load, but should run fine once it gets going. (Optimization is one of the things I'm working on as I create more of these.)
It's about how to create cross-references in Writer, and what they are.
Note: The video uses the Navigator (press F5) to get around more easily to various headings being referenced. The Navigator shows you the structure of your document and the objects in it. By "structure" I mean that it shows all the text to which you have applied the paragraph styles Heading1, Heading2, and so on. More specifically, it shows whatever you have set up as the paragraph styles defining your documentBy structure under Tools > Outline Numbering. That's a whole nother topic, though a very useful one. To learn more about outline numbering and the Navigator, see these blog entries.
One of the great things about OpenOffice.org is that you can open corrupted Word files with it. Or Word files that are just too big to open in Word, open fine in OpenOffice Writer.
However, every so often you will get a rogue OpenOffice file that just won't behave. It crashes constantly, or behaves in other ways that just don't make sense.
In that case, the best approach is surgery.
