Plugin API: Parts and Tracks

(1) Does Part 0 always contain the first stave on the page?
(2) Is Track 0 guaranteed to be in Part 0 or can the track number and part number change independently?

I'm not sure to completely understand your question.
What I can tell is that track 0 is the first voice of the first instrument available(*) on "part" (**)

(*): be it visible or not.
(**) : "part" being here the main score or excerpt

E.g. The same note on appears as "track=0" on its dedicates part:
part4.png track0.png

and as "track=8" on the main score :

Thanks, that is what I am asking, although by parts I only meant different instrument staves in a main score, (guitar part, oboe part, cello part etc). I have never used the type of multi-tabbed parts seen in your pics.

So, if I understand correctly, moving an instrument up or down in the Instruments dialogue will change its part number in the main score and also its corresponding track numbers.

Definitely. by +- 4. (so track 0 (i.e. voice 1 of first staff) could become 4, 8, ...)

I recommend you using an analyser plugin to understand how every thing reacts when moving/hiding instruments, when dealing with multi-voices, or parts ("excerpts" in the API language). There are several such plugin.
The one I used for the screenshots is my own analyser Element Analyser.
