Hello,
You're not obliged at all to use ObjC as the API for what you're asking is C++ - at least concerning the sample rate changing. I've never felt the need to change the default output device, so I cannot comment on that.
Have a look at the DefaultOutputUnit example, it's what I used to write my sample rate plugin for iTunes.

Of course these are written in C++ and I am having a difficult time getting them to work. I am new to Objective C but it seems I may need to learn two new languages to make this work.
