Thank you, I appreciate knowing that those mods work well together. Additionally, could you please give an idea about what functionality is present and working… 1. LNAV? 2. VNAV? 3. TOC marker? 4. TOD marker? 5. Altitude prediction marker (arc along ND route showing point at which the aircraft will arrive at dialled in altitude using FLC/VS mode? I’m sure that for many potential CS B777-200 customers who, like me, aren’t sure whether to take the plunge, any insight into system depth will be very useful indeed.

This is easy for you to test before buying.  Go fly the default MSFS 747-8...that is what this aircraft is by default.  There is no system depth that is of CS's coding....the is their 777 model using the default 747-8 code, simple as that.  ;)  So if your list of items works on that plane, it will work on this one.
I suggest you read around in other forums to see how customers are using mods to make the plane more like a 777.
