What do I do?

[Brian Towers]

FIDE has a definition of sorts in its "Regulations for the Titles of Arbiters" -

Only Swiss System Tournaments may be accepted in case that at least one (1) of them is an international FIDE rated chess event with at least 100 players, at least 30% FIDE rated players, and at least 7 rounds.

Which means that if you get an arbiter norm for an event like this you are excused the requirement to have norms in at least two different types of event - Swiss, round robin, team.

This would have to be standard as elsewhere more restrictive clauses apply to rapid and blitz.

and again

International FIDE rated chess events with at least 100 players, at least 30% FIDE rated players, and at least seven rounds (maximum one norm).

This is quite something as otherwise IA norms have to be for events of a standard where playing title norms are available rather than your bog standard weekender.

Is there a FIDE law about the4 number of arbiters for a tournament?

One of the fide recommended books seems to be joe Gallagher's "chess combinations" as the title it reads in Russian. Which one of his books is it?
