My firmware .bin files are labeled "01.08.01.00." I believe the Go App reports the firmware as 1.8.1.40+. I don't have my Inspire 1 with me at the moment, so I'll have to check next time I'm at my house. I'm 90% sure about the FW versions.
I assume you have the X3 camera. The X3 CAM firmware will always match the AC firmware. The same is not true for the X5 CAM.
The firmware you have should work extremely well. I don't think the .40+ at the end will make a difference. But give me a couple days to check my FW version.
Regarding your RC FW conundrum, there's nothing wrong with running FW v1.7.60. There are 3 different controllers for the Inspire 1. A, B and C. This letter will be at the end of the controller model number. For example, "GL658C." I would bet money you have C, as it is my understanding that the A and B will only work with FW v1.6 with the legacy AC firmware you have installed. The C works with both. I have all 3 controllers, but haven't fully experimented with the FW numbers. I believe at this time I am using my "C" controller with FW v1.7.60. I will have to check.
Go App (forgive the rant)...
Regarding your Go App, I recommend v3.1.1. Anything newer than v3.1.1 is spyware. Some don't mind. I do. I do NOT send my flight information to DJI. Autonomy is important to me. The version you have will force you to login to the DJI mothership. This may randomly pop up when you're miles from WiFi or cell service. DJI won't let you fly until you log in. This bit me once. Never again.
Allowing DJI to track you may be something you don't care about. Most pilots probably don't care. But it's a huge deal for me. I relish my autonomy when I fly. I follow all the laws and the rules of course, but you will find that DJI GoFencing restrictions can be erroneous; grounding your drone in perfectly safe Class G airspace. This happened to me on one job one time. Never again. I have completely severed all ties with DJI. I purchased the Inspire 1. I OWN the Inspire 1. If I were renting the Inspire 1 from DJI, that would be a different story. I think you get my point.
All that said...
The firmware combination you have is a good one and should work extremely well. I would roll back your software to v3.1.1. I use iPads. If you're using Android Tablet, you'll have to find the Android equivalent of Go App v3.1.1. I BELIEVE the version numbers are the same. But I don't use Android, so I don't know. If you're using an iPad, rolling back software is NOT a "user friendly" process. It's a hack. Until I know more about how you are using your drone, you may not want to go down that rabbit hole.
Unfortunately (or fortunately, depending on one's point of view), there is a TON of information available on this stuff. Fortunately for you, I'm a pretty good source for Inspire 1 information. I fly my Inspire every week and have for years. I love it. She still continues to make about $1400/month residual income for me every month like clockwork. Not a lot of money, but it's one flight per week. So it's not a big time investment. And honestly, I love doing it. So there's that.
Unfortunately, I set her up years ago and haven't had to mess with her since (a testimonial as to how rock-solid the platform is). So it's been a while since I looked at all the nomenclature. Next time I'm flying my Inspire 1 I'll be sure to get a screen shot of my FW numbers. Rest assured, the combination you have right now will work extremely well.
Best of luck.
UPDATE: I found a screenshot of my FW versions. This is with the X5 camera.

This may be an older screenshot with a different controller. But the important thing is the AC FW, which aligns with what you have.
