What follows is my best, heart-felt newbie advice, but its a lot more Zen monk and a lot less Bruce Lee than maybe you were hoping...
First, lock picking is about patience and practice. Since it looks like you are itching to go and you have a good beginner's lock, so start by placing your order for some picks.
If you have a $20 plus shipping go for this nice little kit:

If you just want to buy individual items, that hook is fine.
Here is a nice snake rake:

And a decent, generic tension wrench:

Now, since the post office doesn't teleport items yet, go the FAQs and general information section of LP101 and gather as much info as you can. I got started with the MIT guide to Lockpicking (just Google for it) and it is a great, free document.
Now read the MIT guide.
Next, sit down with the guide and start looking at your lock. Get a flashlight and try to see inside. If you are lucky you might be able to see the top and bottom pins on the first pin in the lock (don't worry if you can't, it is just too high for you to see). Get a bobby pin or a safety pin and bend the end up and use it as a probe. Press the pins and start to get a feel for how the pins move. If you have the key, insert it slowly and turn the lock, remove it and do it again. Why? To start learning about the feel of the lock. Does it feel a little sloppy, or tight like a precision machine? Can you wiggle the pins a little back and forth? How much pressure do you have to use to move the pins up. How much pressure does it take to turn the key in the lock? Try to count how many pins are in the lock by sliding straightened paper clip into the lock, press up on the pins and slowly take it out while listening for each pin to snap back into place.
Now read the MIT guide again, look at your lock some more, try to find some more locks for free/cheap (garage sales, ask neighbors, dollar stores, Walmart) and wait for your picks to arrive. When you get them you will have a much better idea on what to do with them AND have started to develop the skills you will need to pick locks far beyond that Kwikset.
