This is pretty simple to do via the UCSC table browser. In brief, make your
probes into a custom track. Then ask for the overlap of your probes with
exons, etc., in the Table Browser. For more detailed instructions, there is
a link on the UCSC pages to contact them. Just copy your email to them and
they will likely give you step-by-step instructions on how to do what you are
asking within a few hours; they are quite helpful in general.
An alternative is to use the Galaxy server here (which seems to be down at
this moment):

Hope this helps.
