This may be obvious, but here goes: When I e-mail a firm, and they (inevitably) reply with "We haven't made a decision about summer employment blah blah, but we'll keep your resume on file," there's no need to respond to this e-mail, right? Obviously all I would have to say is "thanks!", which is not very necessary, plus I don't want to clog up their inbox or waste their time.

Tell me I'm not overthinking this...

You COULD reply with something more than thanks if you didn't have a cover letter with your resume (say something along the lines of "Thank you so much for your help, I am really interested in x, y, z, at your firm and look forward to hearing from you in the future"

Or you can leave it as is. Both are acceptable.
