Looking into PyObjC memory usage is on my todolist, but I haven't gotten around to doing the work.

Is the memory use bothering you?

No. PyObjC is released with the MIT license and that allows you to use it in closed source software.

I'm not a lawyer and haven't studied the AppStore requirements, but as long as you own the copyright on the application itself you can  relicense your code as much as you want and hence sell it on the AppStore.  I'd be carefull w.r.t. including (L)GPL-ed code in your application though, the iOS appstore requirements are incompatible with that license and I'd be surprised if the OSX appstore were any different.
