The ippqj-5.3.dll error is a known bug which can be solved by reinstalling the one package in osgeo4w that relates to it. No un-installation is required when working with OSGeo4w normally. However if you wish to uninstall simply delete the C:\OSGeo4w folder. OSGeo4w has very few registry entries (1-4 I think) If you got QGIS 1.7.3 and QGIS 1.9.90 you probably did a full install of everything in OSGeo4w. Which means you got the stable and the development versions of QGIS and a whole lot of other stuff. It also means you got a lot of other stuff that sometimes doesn't behave right all together (an unsolved puzzle). The suggested method would be to use the Quick/Simple setup option to start, and then re-run the setup.exe as you discover you need additional libraries for programming purposes. I'll make sure to post a guide I wrote up for my students doing QGIS python development later this week which will give a good sense of what else you might want.
