First of all, many addons will not work unless obse is installed. Also, in order to take screenshots in game you need to edit a line in your oblivion.ini file. This is located in the folder I mentioned in my first post, and the line you need to edit is "bAllowScreenShot=0" to "bAllowScreenShot=1". Also, some of the addons you're trying to use require more than just OBSE (oblivion script extender). The motion blur one requires OBGE (oblivion graphics extender), OBGE also requires OBSE. Confusing, right? You don't need wrye bash, but I highly recommend OBMM (oblivion mod manager). This is a good program for managing mods, load order, and will also open oblivion with OBSE so it makes things much easier. If you do want to install wrye bash, however, I can confirm that it DOES work on windows 7. The only thing you need to watch out for is that the bundled python install that you downloaded from the wrye bash page on tesnexus doesn't install everything. There will be another exe in the temporary offline install folder that you need to run manually before actually installing wrye bash. If you want more detailed help with this later on you can PM me and I'll do my best to explain it to you.
