If you have never worked out, or know very little about working out, I would suggest hiring a personal trainer for a couple of weeks who can teach you the ins and outs of weight training. If money is tight you should pick up some magazines or a book. I subscribe to Muscle and Fitness, which is quite good. The main reason to use these is that people who first start working out invariably have horrible form which leads to ineffective workouts and may lead to injury. Inform yourself before you lift.
As a beginner you should concentrate on basic workouts such as bench press, military press, sqauts and deadlifts. Don't be afraid to use freeweights, they are your friend. At first concentrate on your form and don't worry about how much weight you are lifting. That will come in time.
Oh, and don't believe in fad workouts - they're crap.
As a beginner you should go maybe four days a week (ideally two days on, one off, two on and two off). Try to hit one major muscle group per workout (back) and follow it up with a smaller muscle group (biceps).
No, in all these things we are more than conquerors through him who loved us. For I am sure that neither death, nor life, nor angels, nor principalities, nor things present, nor things to come, not powers, nor height, nor depth, nor anything else in creation, will be able to separate us from the love of God in Christ Jesus our Lord - Romans 8:37-39
