1) In my experience, a Nuke artist transitions to Fusion quite quickly, especially if the Nuke2Fusion bundle from Reactor is installed—this is a set of hotkeys and macros that make the Fusion environment much more familiar.
I've trained several Nuke users, and they can be doing general comp tasks within hours. Maybe two weeks for a mid-level artist to become about as proficient in Fusion as they were before. I've never assisted a Flame user's transition, but we did have two Flame artists who joined our company at the same time I did, and they didn't seem to have any trouble (I was transitioning from Nuke at the same time).
Someone coming from Nuke might struggle at first with the channels paradigm—Fusion doesn't have anything like Nuke's arbitrary channel system that you can pass down the pipe—you wind up with more parallel wires to bring mattes and so forth downstream. And people who have done a lot of projection or other 3d work might find Fusion's 3d system constraining. I never got very deep into Nuke 3D, though, so I'm not sure where the pinch points will be.
2) I've never tested both programs on similar materials side-by-side, so I can't quantify the speed differences, but Fusion has always felt faster to me. Maybe that's because it doesn't tease you with that scanline slowly drawing the image—you get the whole frame at once. Or maybe it actually is faster; I don't know. Stability seems about equal, although that can depend greatly on configuration and how you use the tools. I've had a lot fewer licensing headaches with Fusion. Plug in the dongle; done.
Capabilities are broadly similar. Fusion doesn't have Weta-style Deep compositing tools, and there are some plug-ins available for Nuke that aren't offered for Fusion (KeenTools, for instance). I've not heard of much that Nuke can do that Fusion cannot. Any it's easy enough for a competent technical artist to reverse-engineer most Blinkscripts or Gizmos into Fuses or Macros. I've done that a couple of times, and I know there's somebody else working on converting the most popular gizmos.
3) Mocha is magic. No question. I would recommend that you also plan on eventually adding a dedicated 3d tracker, also. Syntheyes is affordable. I use PFTrack, but it's pricier. Fusion's CameraTracker might suit your needs for a while, but it definitely has its limitations. Both Syntheyes and Mocha can export Fusion nodes without the need for additional plug-ins or scripts. I think the folks who make Silhouette were also working on a Fusion export module. I'm not sure if anything came of that.
4) From your questions, I'd say yes, the Standalone is a must. The Fusion page integrated with Resolve can do some cool stuff, but for visual effects tasks, it's better to run without Resolve's significant resource overhead. And comps in Resolve's Fusion page are locked up in the database instead of being discrete files on disk, so they're both less robust and less flexible.
I haven't tried to build a Resolve -> Fusion pipeline yet, so I couldn't say how nice the interchange is. I'm sure there are others out there who could tell you more on that score.
And finally, I second the recommendation for both Sander and Eric—they're both extremely knowledgeable and good teachers.
