When I move things like my book dedication to the center of a blank page and then upload it, my previewer shows it at the top of the page. How do I get it to remain in the middle?
It's rather hard for anyone to answer you if no one knows what you're doing. The general answer to your question is to properly format your text and to remind you that e-books don't have pages. If you're using Word, the answer is to use Styles to format everything and not the spacebar or return key.
The best way to format your ebook in Word for KDP upload is to ensure that you embed all text styling and spacing within named paragraph styles in Word. If you are currently using multiple blank spaces caused by the enter key then you are doing it wrong -- which is why you are having problems. To become fully acquainted with all the rules for KDP upload for a Word doc, you should read The Amazon Kindle Publishing Guidelines which you can download from the internet.

Html allows only one space between paragraphs (and one letter-space between words). You can hit the spacebar or Enter key all day, and you won't change anything. The only way to position things vertically is to use margin-top (or top-margin). I do this in html, but you can also do it in Word. Set up a Style for your title, which you should do anyway. Center it horizontally, set it in italics (if you prefer), size it at say 200 percent of normal text, and add a top margin. Name that style and save it for future use.
Believe me, you don't want the title halfway down from the top. I use the following style for the title (it's html, not Word):
So you see that I am dropping it down from the top just 1 "em" -- meaning the same depth of a line as the title itself, which is twice the size of normal text. (You can see exactly how this works by going to the Look Inside of my Guide on the Amazon store. There are also styles for the sub-title (medium) and the author and publisher (small).)
An even better way, if you are building a print edition as well, is simply to scan the title page of the print edition and include it in your book as a full-page image. That's what most Big Five publishers do.
(Don't trust KDP to publish a print edition. Don't trust CreateSpace to publish an ebook.)
