Magic the Gathering, or MTG is a great hobby to get into, and a player of the game myself, it's a really fun way to pass the time.
Finding a place to play MTG is the first step to getting into it, and you've already done that. The next is purchasing a intro pack, maybe two. The most current edition, or block, as it's called, is Zendikar. Zendikar is divided into 3 sets, as are all of the blocks, them being: Zendikar, Worldwake, and the current set, Rise of the Eldrazi. There is also a running set that is released every year, usually called M9, M10, and the upcoming set, M11, set to be released in July. I recommend taking a trip to a local Target store, where they should have intro packs and booster packs of the current sets. If you're looking for something simple to play with, buy a Rise of the Eldrazi intro pack called Totem Power.

Most intro packs will run about $12 - $16, and feature an already built deck, a booster pack, and a set of rules and explanations of keywords and other jargon involved in the game. STUDY THIS RULE SHEET!
I don't recommend attending Super Stars, as it is a bit more higher on the skill ratio than what you're currently playing at, and the players there would probably wait for you to just make a mistake and disqualify you than attempt to correct any mistake you make and chalk it up as inexperience rather than just plain cheating. To find a better suited area of play, use this:

Find one of these casual tournaments and seek out the judge. tell him/her that you are new to the game and want to learn to play. Hopefully, he/she will cooperate (as they should), and help you. Don't be discouraged, as other players will be much more accomplished than you in the game, but you will quickly be talking about the game like you've been playing it for years.
A new Magic player's best friend is this website: http://www.wizards.com/
and you can find out a lot about the game here.
It would help to get a profile on this website:

as it will allow you to participate and become ranked in the MTG community.
Wishing you the best of luck,
Matt
