OK we've taken the plunge

Now we need some advice from the experts
We're getting a Celestron C9.25 XLT OTA in a few weeks and we will be mounting it on our EQ6. We're going to be using our Canon 40D prime focus.
We will be using a William Optics SCT Crayford focuser and a Meade 6.3 Focal Reducer.
We need to know what other adapters we may need to attach them together.
Here is our system
Celestron OTA - WO SCT Crayford Focuser - Meade 6.3 Focal Reducer - Cannon 40D
In which order do we connect them and what extra T Adapter? joiners etc ? will we need in order to reach focus with the DSLR.
I would appreciate any feedback
Thanks David
