I started playing magic again about a year ago so ill offer what advise i can from my experience.
First off if your wanting to learn to play the game find your local card shop and find out if they run Friday Night Magic (FNM) this will be Standard format, Current standard format is Zendikar worldwake and rize of the elderazi (this block rotates out in october). M11 (rotates out soon) and Scars of mirrodin mirrodin beiseged and new phyrexia (these wont rotate till next october).
Standard is effectivley the newest cards and generally the more populour and commonly played format.
Hopefully your card shop will have some people willing to teach you and let you into it gently. Best place to start if your wanting to go down the FNM route, is with an event deck (i would advise against the deck with stoneforges in cant remember the name as you cannot modify this due to the recent stoneforge mystic and jace the mindsculpter ban).
Duels of the planeswalkers is a GREAT place to start its how i got into magic back along, only thing i will say is some of the more complex rules are wrong with duels of the planeswalkers. Activating instants and creature abilitys during combat are a pain in the ass in this game if you are used to playing in real life.
But its a great place to start as already mentioned decks are preconstructed but if your going fnm your best bet is an event deck as mentioned. People who play FNM can be quite competitive as wins/loss's do count for your overall DCI ranking if your intrested in that side of things.
so yeah i guess go for duels first or find a card shop get an event deck and go from there
people are always willing to help and offer advise just be willing to listen 
Woo first post/reply hope it was useful
If people are wondering i'm currently running (i only play standard) BU infect control brian kibler variation, and a green white infinite life gain birthing pod deck (which just got alot weaker with stone forge banning
)
