Awesome! The teeth turn up out of the clay all the time, so you'll find plenty of teeth right off shore. Somebody mentioned Alhambra - that's where to park - so gear up at your car and head about 50-100 yards out anywhere along the sand. Maybe Walter will give you some hints on where to go specifically, but you won't be disappointed on your own.
You don't need any special equipment other than a flag. You should bring something to make a buddy-line with in case the visibility isn't good. I wear gloves (fire worms) and stuff the teeth into them as I find them - a tip picked up from somebody here. Visibility isn't all that great even on good days, and you find teeth in bunches so you probably don't want to be wasting time using a collection bag (except maybe to occasionally transfer your loot to).
Since you will be here for a limited time, you might want to play it loose with the boat... in other words, spend the GOOD days on the beach and the not so good day on the boat. This might be difficult because the boats fill up, but I'd be disappointed having to sit a day out after coming all that way.
