Yep, I got that part figured out finally. Unfortunately I'm getting back 0 results when I pass the shards parameter, as opposed to when it is omited.

http://localhost:8983/solr/select?q=graph&mlt=true&mlt.fl=title&mlt.mindf=1&mlt.mintf=1&fl=id,score,title&shards=localhost:8983/solr

returns:
<lst name="moreLikeThis">
<result name="018639b9dfd5003c20c3ceb29df9d582" numFound="0" start="0" maxScore="0.0"/>
<result name="83de9bc1953e36e44df8e95661983183" numFound="0" start="0" maxScore="0.0"/>
</lst>

where as 

http://localhost:8983/solr/select?q=graph&mlt=true&mlt.fl=title&mlt.mindf=1&mlt.mintf=1&fl=id,score,title

returns

<lst name="moreLikeThis">
<result name="018639b9dfd5003c20c3ceb29df9d582" numFound="1198" start="0" maxScore="3.3357687"/>
   ...result docs
<result name="83de9bc1953e36e44df8e95661983183" numFound="487" start="0" maxScore="4.129801"/>
  ...result docs
</lst>

However, perhaps more pressing is that when the shards param is set my spellCheck component stops responding (I had to apply the distributed spellcheck patch as well). yikes...

I poked around in the code, but couldn't really make any progress.. Any help would be greatly appreciated.
