I've looked high and low without success. Where can i find
something resembling the BNF of Knuth's TeX typesetting syntax?

What symbols are fundamental, and what ones are derived?

Knuths TeX book mumbles something about "registers" that
hold things like page numbers or whatever. Where is there
a complete list of these registers, uses, and limitations?

Knuths TeX book is an abomination, describing lexing and parsing
as mouth, gullet and stomach nonsense.
[Well, he invented most of what we know about parsing, he gets to
explain it any way he wants. Chapters 7 and 8 describe the syntax
operationally. -John]
