You can buy a single ISBN, but it's costly. Blocks of 10 run $250 for U.S. individuals/companies; they can be purchased from Bowker's "My Identifiers" site:
clickety.
Not sure about the reprints question, off the top of my head...
You do not (typically) need to buy the barcode--if you're self-publishing, someplace like LightningSource will do the barcode for you.
But the point of buying your own ISBNs is that you control the info and metadata--that is, you/your company is registered as the publisher, etc. (With someplace like CreateSpace or Lulu, they own the ISBN and the book will always have their metadata attached to it, which marks it immediately as a self-pubbed book--not a problem for everyone, but not everyone knows this.)
Feel free to email me if you want more info--I bought a block of 10 and used the first to do my friend's book (from ISBN purchase to metadata wrangling to editing to typsetting). smileys/smile.gif
One caveat: if you use LightningSource, you really need to know what you're doing; I think CreateSpace and Lulu are more user-friendly for people who've never published/self-published before. LightningSource produces extremely professional results, but they do not offer any real support in building the book (since they're primarily a printer)--I knew this, so I knew I needed to get InDesign and hire a cover designer.
p.s. The three "Bibles" of self-publishing and print-on-demand are:
One
Two
(This last one is not as good as the first one by Shepard, but it does have a few tips that are not in his first one. Anyway, he's good about updating his stuff online, so it's not really necessary.)
Three
Clearly, I could wax on about this for hours, but I'll stop. smileys/wink.gif Let me know if I can help with anything.
