FIrst question: Is the "name" field stored (stored="true")? If it isn't, that would explain your problems with that field. _all_ relevant fields (i.e. everything not a destination of a copyField) need to be stored for atomic updates to work.
Your second problem I'm not sure about. I remember some JIRAs about multivalued fields and atomic updates, you might get some info from the JIRAs here: https://issues.apache.org/jira/browse/SOLR but updating multiValued fields _should_ work...
