Do you have a transmission diagram for your ir-pass filter. I found one from one of your suppliers but do not know if this is relevant or there have been changes. Above all, I want to ensure the damping up to 300nm.
We don't have a transmission diagram for this filter ourselves currently. The base of the filter is a Schott-equivalent absoption glass RG 630 (you can look up its properties in the Schott catalogue). For this reason it is assured that blocking is effective down to 300 nm.

I am interested in purchasing the Universal Alan Gee and the MaxBright II Binoviewer for my Celestron 9.25 evolution, which has a 1.25" star diagonal. Are there any other components I would need to make this setup work?
The 7.5m T-2 extension #2 mentioned on the left side of the PDF is included in the scope of delivery of the UAG, so you can screw the UAG between any binoviewer with T-2-thread like the MaxBright II or the old MaxBright and any of our T-2 star diagonals.
If you have a standard 1.25" star diagonal without T-thread, this will not work to your satisfaction, as these star diagonals do have a longer optical length and no thread for attaching the binoviewer. We recommend a T-2 prism diagonal (they have the shortest optical length) plus the BTA-adapter for Schmidt-Cassegrains # 2408160, which can be screwed onto the back of your telescope, or a 2"/T-2 nose piece #2408150, if you have a 2" eyepiece holder on the back of your telescope.

Any chance you will be making one of these adapters that will work with the Canon EOS M (EF-M Bayonet)? A few competitors of yours have EOS M to T-2 adapters but having one of these that would fit an EF-M Bayonet with a 2" filter in front that can also connect to your UFC system would be amazing.
EOS-M cameras are not common in Astrophotography. We would need to produce thousands of adaptors at once in mass production to make it happen, but unfortunately there is no demand for such an adaptor, your inquiry was the first ever.
