Hi Fred, I think indeed the source of your problem is the mixing of different versions of python: the one in osgeo4w and the Conda one. When SIP is not loaded correctly, you will not have any python based stuff in QGIS (so no plugins and processing).
The osgeo4w scripts normally 'isolate' the (python) paths pretty good. If I'm correct by actually even clearing your own PATH variable (??) But I think that Conda add's it's path's to your normal (python)path's (PATH or PYTHONPATH) variables. For what I know you should not have to 'fix' things in the osgeo4w scripts, better to make sure your system PATH is not filled with PYTHONPATH's or python/bin dirs in PATH. You could try to start the osgeo4w 'terminal' and check what the environment variables PATH and PYTHONPATH are there. If you see conda-paths in it, these should be removed (either by removing them from your environment (but then you have to 'fix' conda) or by clearing them in the osgeo4w bat files...
