The general rule of thumb for Swiss tournaments is: N rounds for 2^N players. For up to 16 players, 4 rounds; for up to 32 players, 5 rounds; for up to 64 players, 6 rounds; for up to 128 players, 7 rounds.
The most important check is confirming active attendance. Any pre-registered player who did not show up in person must be marked Inactive or removed before generating Round 1 pairings to avoid ghost pairings.
Under FIDE regulations, the tie-break hierarchy must be announced before Round 1 starts. The standard order is: 1) Buchholz Cut 1, 2) Standard Buchholz, 3) Sonneborn-Berger, 4) Direct Encounter, 5) Greater number of wins.
