As far as I understand it (I am not a licensing expert) yes. But the 
commercial Ext license is on a per developer basis and not really 
expensive (see http://extjs.com/store/extjs/).

Yes and no. Many GeoExt components (GeoExt.data.*) only depend on Ext 
core. But as soon as you want an Ext based GUI (and if it is just a 
MapPanel), you will depend on ExtJS.
