As mbovenka says, the Hanlin V3 clones are your best bet for meeting those standards. You might check out the Astak EZreader section of the forums. I believe it's a Hanlin V3 clone (I'm pretty new here, so don't trust me 100% on that, do the homework).
The other alternative (and one that would probably take a while but be worth it down the road) is to convert all the lit files (or at least do one at a time as you need them) with Calibre. I'm looking into a Jetbook Lite or an Aluratek Libre Pro since they seem to have nice firmware, but I've got a lot of .lit files, too. It's going to be a long road, but I'm just going to have to use Calibre to convert them all.
The Jetbook lite does quite a few of the things that you want. From their website:
* Support of Adobe DRM, ePub, Mobi, PRC, RTF, .txt, .pdf, .fb2, .jpg, .gif, .png, .bmp and html file formats
* Support of eReader (PDB) DRM format through Ereader.com and Fictionwise.com
* Pre-loaded with the top 100 favorite classic ebooks
* Perfect pocketable size
* Support for eBook contents in Albanian, Arabic, Catalan, Danish, Dutch, English, Faeroese, Farsi, Finnish, French, Galician, German, Hebrew, Icelandic, Italian, Norwegian, Portuguese, Spanish, Swedish, Croatian, Czech, Estonian, Hungarian, Latvian, Lithuanian, Polish, Romanian, Russian, Slovak, Slovenian, Vietnamese and other languages.
* Bidirectional cross-dictionaries between English, German, Spanish, Polish, and Russian
* Multilingual interface options
* Pre-loaded CIA World Factbook
* Bookmarks and auto page turn functionality
* Adjustable font type and size
* Screen rotation support for both portrait & landscape modes
* SD card slot (expandable up to 32GB)
* Batteries 4xAA (rechargeable batteries can be used as well)
* Free firmware updates available at

From what I've read, they work well with folders, so that they're somewhat easy to organize and quickly get to the books you want. I don't know if you care about the differences between a reflective lcd screen and an e-ink (the reflective lcd won't have that glitchy fade to black business when you turn pages and the page turns are basically instant, but the e-ink pearl is said to look a little bit nicer than the jetbook's screen) but it sounds like the jetbook is close to what you're looking for (well, minus .lit, .doc).
Just some food for thought.
