The User Guide has a list of all the supported well-known names for marks:
http://docs.geoserver.org/stable/en/user/styling/sld-extensions/pointsymbols.html
The SLD Rotation element supports Filter expressions as content, so you can
use the Sub operator to compute the angle from the heading:
<Rotation>
<ogc:Sub>
<ogc:PropertyName>heading</ogc:PropertyName>
<ogc:Literal>90</ogc:Literal>
</ogc:Sub>
</Rotation>
