You have at least two choices:

(1) Use Layer.WMS instead of Layer.MapServer. With minor modifications
to your mapfile, it is easy to use MapServer as WMS (see
http://mapserver.org/ogc/wms_server.html). I think this is the best
option, because it will build the legend automatically from
GetLegendGraphic requests.

(2) Use a LayerStore with a legendURL field. For each layer, you have to
provide a URL that points to a legend image. This option may only work
with the current trunk version of GeoExt, not with v0.6.

Regards,
Andreas.
