1.1> Absolutely. The filterCache is simply a map. The key is the fq clause, so fq=field1:(1 OR 2 OR 3) is different than fq=field1:(3 OR 2 OR 1).
2.1> not sure. But don't get very hung up on queryResultCache. It's useful pretty much for paging and the hit ration is often very low as it only gets used for the _exact_ same query with a different rows parameter. And it doesn't store the full result set, just the size configured in solrconfig.xml. Mikhail was pointing you to the admin>>core>>plugins/stats>>cache>> page. You can fire your alternate queries and filter queries at Solr and examine the filterCache and queryResultCache numbers before and after.
