Are you planning on doing the full lifts or just the "power" varieties? In either regard, make sure you learn them right. Don't be that guy that hefts the bar up with his shoulders and catches it on straight wrists, you just look silly.
There are many resources online and one can teach themselves sufficiently from watching videos and stuff, but it's a pretty large investment. I would suggest picking up Olympic Weightlifting: A Complete Guide for Athletes & Coaches by Gregg Everett as it teaches the fundamentals effectively and in order.
For programming, it depends on your goals. If you're looking for strength and speed, train like an olympic lifter. That is, you'll have entire days of just C&J, snatch, and squats and fill off days with accessory work like pressing and benching. If you're looking for hypertrophy, the lifts won't really do much for you beyond increase your coordination.
Please DO NOT try to do the lifts for high reps a la crossfit or to try to induce hypertrophy. The C&J and snatch are some of the most technically demanding movements you can do and by your 4th-5th rep you will almost certainly not be doing them correctly. Besides just training yourself to do them poorly, you increase the chance of injury exponentially.
Edit: and ignore anyone who teaches you to "triple extend."
