Keyboard? - as stated in other posts, its can be quite useful. In addition to taking notes, it allows entry of text in fields when using the web browser (searches, email, site logins, ...). There are also a few hotkeys functions available when reading or viewing pictures.
Text-to-Speech? - This functions with all Kindle and MOBI format books unless the publisher has tagged the book to prevent access to the feature. You can use earphones if you want, but don't need to as the Kindle has its own spearkers.
Wi-Fi vs 3G? - WiFi is preferable when available. Its faster and free. 3G downloads can incur fees and is much slower. The only advantage to 3G is coverage. I use my K3 almost exclusively as an ebook reader. I don't make any real use of it as a general purpuse computer/slate. As a result, I have little or no use for 3G. I can always wait until I'm home or at a hotspot to download.
