Negative boosts are accepted, though rather "unusual". Also note that Lucene by default filters out any hits with scores <= 0.0.
Normally you'd set boost to something > 0.0 (0.1 should work). What unexpected effect are you seeing? If you omit norms, then indeed your per-doc boost (and per-field boost, if used) are discarded (have no effect).
