EDIT: Also, where can I find an ISO?

At the moment you'd have to create it yourself using the UUP to ISO process:
UUP to ISO - Create Bootable ISO from Windows 10 Build Upgrade Files

However I reckon it's quite likely official ISOs could appear here soon:

What I do not understand is why they simply did not number it 16300.0 - the only thing I can think of is that Skippy builds were 163XX and they were trying to stay away from 163XX numbers to avoid any confusion (either that all their internal documentation was predicated/promised around version 16299 and it is too late to change it -LOL)

I imagine it was just sequentially numbered as the build after 16298, and then it turned out to be good enough to release. It's better practice to number things sequentially and not try to embed meanings in codes/numbers.

As far as I know, this is a first - a full in-build upgrade - does this mean even when RTM, MS could do that e.g. if they got an issue that could not be fixed via normal cumulative updates?

I seem to remember one of the earlier Updates (Anniversary or Creators?) was similar and there were significant Cumulative Updates on top of the original build by the release date?

If it is genuinely RTM, it will appear soon probably using normal Media Creation Tool - that is what happened last time - the MCT was updated before the official release date.

I downloaded the Insider ISOs for Creators Update when it was in Preview, and then the official MCT ISOs later.
When I was running a duplicate file checking programme to try to free up space on the computer, it said the Insider and MCT ISOs were identical.
So they may release ISOs like that again?

Upgrade from Win10 v1703 to v1709 build 16299.15 in 20 min. everything is fine :)
