If you don't use a lighted cover, the one accessory that you definitely need is a reading light, at least now and then. My favorite clip on reading light is the Mighty Bright that I picked up a few years ago (it is tremendously brighter than the ones I'd had before). Looking thru the ones available now, I may pick up upgraded version, the Mighty Bright XtraFlex2 Clip-On Light. It does look like it may be a bit heavy (it uses two AAA batteries), but there is a lighter version, the Mighty Bright MiniFlex Clip-On Reading Light for Kindle and one from another company that even comes in colors (graphite, white, turquoise and red!), the Verso Clip-On Reading Light for Kindle.
Updated to add: I just saw a video review of the Belkin Clip-On Reading Light for Kindle (white; also available in black) and I may get one of those, instead. Looks quite bright, uses AAA batteries and has three Super LED's, plus the front section is small enough to use on a naked kindle without obscuring the screen, as some of the others do (note that if you have a case, you can clip to it, behind the Kindle, so the clip length in front isn't as big an issue).
