If you are talking about surf-fishing, here are a few things you will need:
1. A long pole; 10-12 feet is ideal.
2. The amount of weight you need depends on the current. Try out 4 oz. if the current is strong. If that is too much or not enough, run to the store and grab some more.
3. Whenever I go surf-fishing, I always use shrimp and/or cutbait. I'm not real experienced when fishing with lures in the ocean.
Bottom rigs similar to http://www.walmart.com/ip/Hurricane-Bottom-Rig/16877499 are good when surf-fishing. You may want to buy some heavy duty bottom rigs though just incase you hook a fish that is bigger than expected.
