Not really... Openings are one of the least useful things to learn in chess outside the master levels... You only need to really learn openings until its not the main reason you aren't losing anymore (which isn't much, its basically a matter of not falling into traps). Besides, since they are all memorization, openings really only teach you openings.
Most important is learning chess tactics (like how to fork, skewer, pin, checkmate, and whatnot). In the words of ken smith: "Until you are at least a high Class A player: Your first name is 'Tactics', your middle name is 'Tactics', and your last name is 'Tactics'." Being able to see how to get an extra piece more often is so much more important then a +/- advantage out of the opening.
Another important thing to learn are endgames. Do you know when you can win when you have 2 kings and a pawn? How about 2 kings, 2 rooks, and a pawn? (lucena position) Do you know when its a draw? (philidor position). Endgames might not come up much at the beginner level, but its a crying shame when you are up a pawn and can't win a game of chess, since these endgames listed come up in over half of the games that simplify to an endgame.
Finally, a bit of study on the middlegame makes for a well rounded study, but still probably 90% of your time (I'm serious) should be spent on tactics until you aren't dropping pieces due to tactical combinations.
I practice on my board, alone, moving both the white and black pieces from a published book on my favorite opening. I'm trying to memorize as many of the opening moves as I can. Is this a good procedure?
