Does the wifi version mean you can only read books while you have internet access, or that you can only download the books while you have internet access? Basically, if I already have the books on the wifi version, do I need internet access to read them?
You don’t need internet access to read books that you already downloaded on the Nook. The internet access is just used for downloading books anywhere with wireless coverage. If you are comfortable with downloading books to your computer first then to the Nook, both versions make not much difference for you.
BTW, I’ve given a detailed comparison between the Nook and the Kindle previously, in another answer here. Guess it’ll help you decide which one to choose:

The international support of the Kindle means not only it can buy books through wireless without connecting to the computer, but also it can have web browsing through wireless to access websites like Wikipedia.
And recently, Amazon has announced an upgrade to its Kindle, to secure their market shares. See here for the update details:

It is just the difference of whether you’re able to download books wirelessly, or you need to download books through your computer first. With 3G version you can get books without using a computer.
Not sure if it helps, but I own the Kindle. If you ask me to choose again now, I’ll still go for the Kindle instead of the Nook, because it has the text-to-speech function which means I can "read" books with my hands and eyes free to do other things. I use this function often when I’m on public transport, doing housework, etc. It is really a cool feature that cannot be missed.
The web browsing function over wireless network on the Kindle (while the Nook only has web browsing over WiFi, i.e. only when you are around WiFi hotspot) is rather important as well. The free internet (and now it is free international internet) plus the web browser allow me to look for information whenever I’m in need. And right now it is free for both the U.S. and many other countries, it is just incredible when you bring it to trip.
And indeed, the Kindle has more available books, and ebooks are cheaper on the Kindle as well (Barnes and Nobles always count in the one million free books from Google, which can also be read on the Kindle. For Sony, many users complain it is difficult to find books for it).
And I remember I read these reviews when I decided to get my Kindle:

And below are the millions of free books and full list of bestselling books for the Kindle, that you can check from time to time:

Finally, in case you don’t know, Amazon just put a big price slash on the Kindle, and it is now a good time to get it. I put the link below for you to check it out yourself.
Hope it helps
