1) writing is the normal burning that you do with a cd-r. RE-writing involves a slighty more expensive cd-rw disc which can be written to and erased over and over again. the rewrite speed is the max speed that can be written to a cd-rw disc. but keep in mind cd-rw discs that are 32x compatible are quite rare. even 24x discs are hard to find, as far as i know. so your rewrite speed is likely going to be limited by the disc itself.
2) you can look at those items at newegg.com and see what comes with it. both the retail and oem come with nero express. the retail comes with one cd-r and one cd-rw disc.
and 52x32x52x is the fastest i've seen from anyone.
52.32.52 is probably the fastest they will come out with for a LONG time, if not ever. mostly due to the fact that when a cd spins fast enough it will actually break inside the drive causing some serious damage. I believe that even the newer 52x drives have a feature that slows down the CD as it's spinning every once in a while. Their main concern now is probably boosting the speed of DVD writers and re-writers.
Retail usually comes in a box, has a longer warranty, has screws and hard drive cables included, and Nero Burning Rom (if it's a Lite-On, anyway). It's not difficult to install. All you have to do is plug in the power cable, drive cable, and make sure the master/slave/cable select jumper is where you want it.
The boxed version usually doesn't cost much more than the OEM, and you actually end up saving money and time buying boxed if you don't already own the cables/screws.
that's the only difference between between retail and oem; the cd-r and cd-rw discs. they both come with software and neither comes with screws or extra hardware. i'm pretty sure the warranty is the same on both, too.
