Hello Mike,
1) I've chosen to shoot RAW 4.6K in 4:1 compression over shooting UHD (3840x2160) in ProRes 444 simply because you get more recording time per card in RAW over ProRes 444 at UHD. Secondly, you can shoot 60 fps in 4.6K RAW 4:1 easily on one card. 4.6K RAW needs dual card mode for 60 fps. When it comes to UHD ProRes options, you'll find that ProRes 422 HQ will get 60 fps in UHD but ProRes 444 gets 40 fps in UHD. As I said, it makes more sense to just shoot RAW at full resolution at that point. I rarely ever shoot UHD ProRes 444 over 4.6K RAW 4:1.
2) Based on the limitations of recording UHD ProRes 444 mentioned above I would venture to say that with the SSD Module you would not be able to record ProRes 444 XQ at 4.6K at 60 fps. My best guess is that 4.6K RAW 4:1 at 60 fps would be your best recording option on the SSD Module. However, since I don't use the SSD Module I have not kept track of what it is capable of recording via RAW frame rates.
I hope this information helps. Overall, you'll find that once you start recording images in RAW you'll never choose ProRes over RAW if you have the option. The video I shot yesterday was in HD ProRes 444 since the client didn't demand anything more than HD. That was the perfect time to use ProRes 444 for the most color and light information from the image.
