for <1>. Not that I know of. What you can do, and relatively simply at that, is create a SolrJ program that uses Tika to parse the files on the *client*. At that point you can do anything you'd like, including detect language, route the document to the right core, etc. This will also give you more control over how meta-data parsed by Tika is mapped to your documents.
about <2>. This is hard, mostly because the queries have very little text to analyze. Consider not worrying about it, just send the query to all the languages in the hope that anything language specific is scored higher. You can do things like detect the language the browser defaults to or ask the user to provide a "preferred language", but trying to determine the language based on a short phrase is notoriously hard.
