Hi there Kim!
First off, I would NOT recommend doing a full body weight training workout. Splits are much better - the easiest split is two days - upper body & lower body.
You should really check out Krista Scott Dixon's website at
http://www.stumptuous.com/weights.html for some GREAT suggestions - if you're someone who prefers to use books, I've just reviewed "Weight Training for Dummies" and it strikes me as a great beginner's book - your library might have it.
At Krista's website there is an article at
http://www.stumptuous.com/program.html called "Krista's Kompleat Kompendium of Workout Routines"

that you should take a peek at...I love the way she begins the article:

I get lots of mail about what routines I recommend for people. It's always a challenging question to answer, because there are as many possible routines as there are screaming prepubescent children outside a Backstreet Boys concert.
But, I thought it might be helpful to compile some ideas on a page for you. These routines are meant to be suggestions based on generally accepted principles of training. They aren't the only routines out there. Through experimentation and careful record-keeping, you'll find what's right for you. Please don't write me to tell me I missed things in routine x. These routines are for you to use and adapt to your needs, so they shouldn't be considered to be the final word on the "right" routine. Pick one and use it as is, or modify it as you see fit. The usual disclaimers apply here about checking with your doctor before starting a fitness program, and making sure you're doing the exercises with correct form, blah blah blah.
There is one constant in the routines on this page: there is no high-rep training with low weight, "toning and sculpting" workouts, or circuit training. You'll never find those useless heresies on this page. Basic, compound movements with significant weight resistance is the only way to go regardless of your goals and abilities, and don't let anyone tell you differently (obviously while you are learning, you are not expected to do huge quantities of weight, but the weight should be a challenge for you). You can do a trillion leg lifts with a pink ankle weight, or you can do one set of heavy squats. It's your choice; make it a good one.
Personally I am currently doing a four-day split - most days it takes me about 30-35 minutes to run through (with the exception of leg day which takes longer). Here's my current split:
Monday: Legs
Tuesday: Back and biceps
Wednesday: Shoulders/Abs/Calves
Thursday: Rest (cardio only)
Friday: Chest and Tris
On Saturdays and Sundays, I have riding lessons and prefer not to do weights the same days (I ride hunt seat and do a lot of 2-point riding - riding with my butt out of the saddle - like being in a squat position for 5-10 minutes at a time!).
Hope this helps - feel free to stop by anytime
