It all depends on the thickness of your total materials. Glass for instance will be either 1/16 single strength or 1/8" Double strength. My guess would be approximately 3/8" but again double check the total of the material being used before you cut your rabbit. Glazier points should work fine for holding your back in.

Last frame I did I used 1/2" for depth and 1/4" for width. Generally I prefer the frame to be at least 7/8" thick material so that I can have nice bevels on the inside as a reveal.
Single strength glass, double mat, mounting board + 1/4" MDF to make sandwich. Ended up flush and I prefer to use the little brass turn-buttons for stuff up to 11x14. Easier to mount and less likely for me to bugger things up than trying to push in glazer's points in hardwood.

If you use glazier points, do you need to make the rabbet deeper than the combined thickness of the glass/matt/backing, to allow room to install them?

You will make a "sandwich" of the single strength glass, the mounted image and the backing board. You will need to leave enough room for the glazing points. But picture frames are usually make from fairly soft woods and I am not convinced that you will be able to drive the points into the hocky sticks (ash?) which has to be a pretty tough material.
You might be better served securing the image from behind by gluing a sheet of black mat board. "Paint the edges of the mat board with a black magic marker to make it dark.
Adhesive transfer tape (double faced tape without the carrier) will work fine for this. You may have to pad the sandwich to fill the available space.
But first check to see if you can drive the points into the hockey sticks. If you can you should ignore all I've said above.
The alternative is to make the frame with no rabbets and then glue 1/4" stock to the rear of the frame to create the rabbet. This will give a full-depth frame out of the hockey stick and may look better.
