Welcome, indeed!
There are quite a few Kindle users on the forum. And, the generous people who create books have posted over one thousand for the Kindle, right here at MobileRead. When you get the Kindle, be sure to download the
MobiPocket Download Guide. With that, you can download any of the books here at MobileRead directly to the Kindle through the Whispernet services.
Hope you enjoy your Kindle as much as I'm enjoying mine.
