Go to your LBS and see if you can find an old short-reach, hi-riser quill stem with 26mm bar clamp as most drop bars are 26mm. Some LBS's have them laying around in their junk box. Other than that, you should be A OK... I assume you're running a 7-speed. A new (old stock) Ultegra 8-speed bar end shifters will work just fine. Oh, and forget about installing cable/barrel adjusters, your rear derailleur cable adjuster is all you'll need. That's what I run.
