Let set \( A = \{1, 2, \cdots, 366\} \). If a two-element subset \( B = \{a, b\} \) of \( A \) satisfies \( 17 \mid (a+b) \), then \( B \) is said to have property \( P \).

1. Find the number of two-element subsets of \( A \) that have property \( P \).
2. Find the number of two-element subsets of \( A \) that are pairwise disjoint and have property \( P \).
