If you want your wms layer to be reprojected to EPSG:900913 you should
not use projection:'EPSG:4326' in your wms layer options.

Yes, unless layers define their own projection option, as you do.

No. Actually, the "reprojected" option is not even transferred to the
wms server. It is used internally by OpenLayers.

What people usally do is set a projection at the map level and none at
the layer level.

You should take a look at the sphercial mercator example.
