I'm not clear on why you could not have left your layout as spreads. When you output to PDF, your paired pages will be output as singles (unless you choose otherwise).
If you need inside bleed (not usual for most - only needed for loose-leaf or wire-O printing), there are methods for achieving this without losing your layout.
The un-numbered front pages are easily handled by changing the numbering style of those pages.
If this doesn't answer your issues, please post more detail as to what is going wrong.
The first two pages in the book WERE un-numbered, but converting from spreads to single pages caused automatic reassignment of those page numbers, so that there are now two pages marked “1” and ”2”. I would like to make the first two unnumbered as they were prior to conversion from spread format, or do delete them and start over. When I try to apply master to them or to delete them, inDesign throws an error stating that more than one page has that number.
I’m wondering if I need to refine the spread version prior to converting (?). Or maybe revise the masters to to convert away from spreads? Maybe that will work better?
Go back to SJRiegel's post. WHY do you want to tear up your layout. There is no good reason except for some very esoteric situations that warrant it.
Right, I did go back, reread his posting tried his suggestion, and yes, it worked.

Look in your Pages panel, and post a screen shot if you need to. If you try to use the exact same page number twice, InDesign will scream.
To get the unnumbered pages for the first two pages:
1. assign the none master or another master without numbering
2. in Numbering and Section Options, assign i, ii, ii, iv to those two pages
Trying to fight my way through a new problem set that I seem to have created for myself.
I created my book in horizontal, spread-paired pages for effient preview, and now have to convert to single pages.
The correct way to do a book is in spreads. Always.
