OK so I found the application notes for the Memsic device! The application note for using thermal accelerometers can be found at:
http://www.memsic.com/data/pdfs/an-00mx-007.pdf
It shows the implementation used in the code I wrote and confirms that it should not be used for >60 degrees. The other way around that as explained in the PDF is to use both axis measuring ONE axis. Its a good read!
It also shows the linear method used by the Parallax BASIC Stamp when used with this accelerometer. Luckily the Arduino can use the math.h library ;D .
As for the TOUT, I think you may be able to find it in the other PDF's located:
