Answer 1

Since I don't know what's causing the initial update (i.e. what
exactly you application code does), then what I suggest will be
a guess at best.
Anyway, a row-level trigger will not allow the same table to be
directly or indirectly altered. This is a safety mechanism to
prevent an infinite loop of inserts or updates from occurring.
What you might want to consider instead is to encapsulate your
application logic in a stored procedure that performs all the
updates you require explicitly, with no triggers involved.
