Jon,

First let me say that I agree with your frustration.  A couple of comments,
however:

  a) Everything you wrote before getting to the axioms for Group
     Theory is supposed to be considered background for anyone who
     wants to use logic to talk about mathematical (or any other)
     theory.  Thus, it's a bit of a red herring to complain about
     the weight of machinery involved.

  b) I can't imagine what the machinery would look like to talk about
     our talking about Group Theory in English, for example.  In that
     sense, FOL looks a lot simpler to me.  Did you have some other
     mechanism other than natural language in mind?
