That's a good start. You could refer to the SvxAuthorField as well for 
reference.

You could refer to the code where the slide numbers are reset.
I am guessing it should be called with some Invalidate()

http://opengrok.libreoffice.org/search?q=SvxPageField&project=core
throws up some interesting results for you.

I think you missed,
http://opengrok.libreoffice.org/xref/core/tools/inc/tools/pstm.hxx#SV_DECL_PERSIST

Which is kind of the the first line in the class definition of SvxPageField:

SV_DECL_PERSIST1( SvxPageField, SvxFieldData, 
com::sun::star::text::textfield::Type::PAGE )

Trace it through and you should be able to find out, how it works.

Some kind of refresh needs to occur when the slide orders change - trace 
the pagefield.

You would have to create the idls and create the corresponding services.
The easiest way to start is to copy those files and change it accordingly.

May be you you missed changing some files (?)
Also don't forget to compile modules like officecfg, offapi, etc (afaik) 
- which does the additional work of creating the corresponding C++ 
header files.
The best is to do a 'make' in the root (at least the first time) and a 
fresh make dev-install.

Hope these help.
And its a very nice patch for the first time. I really liked your 
efforts in adding the UI changes as well!

A little more digging and you should be able to complete this.

Thanks a lot for the patch again!
