This could lead me to believe I can use different boost for fields with

You can. The values are multiplied to produce the final boost value for
the field. This is described in:
http://lucene.apache.org/java/docs/api/org/apache/lucene/document/Field.html#setBoost(float)
But you're right, that's not entirely intuitive.
How about refactoring fields to something like:
[Document](fieldName)<#>---- {0..1} ->[Field +boost]<#>---- {0..*} ->
[FieldValue +store +index +termVector]
That would be a big, incompatible change to one of Lucene's primary
APIs, no? Long-term, an API which supports per token boosting will
probably prove useful, as a part of #11 on
http://wiki.apache.org/jakarta-lucene/Lucene2Whiteboard. When this
happens it would probably be worth considering making the change you
suggest, but I'm not sure it would be worth it before that.
