New at all this!! Help!!

Even without the training plan, just hit the pool, ride the bike (bike trainer if it's too cold), and get a pair of good running shoes, (I recommend asics) and hit the road.

Unless you have some kind of endurance sport background it would be a good idea to take up one of the free plans found here.  As other have suggested spend time at the pool on the bike and run. 

Don't get in a rush to do speed work on the run.  Log all of your miles easy as you get ready for your first race.  Don't try to get faster for a run for a long time, just log easy miles and start small.  the impact of running can produce injuries over a longer period of time that will have you questioning how in the world it happened becaue you might not be able to pinpoint a time when something happened.

The other disciplines are alright to work out hard but make sure you have at least some base before you begin doing hard workouts.

In January look for a mentor group.  This will happen at the first of the year and some of the good groups will fill up very fast, so be on the look out on January 1.

And..........Welcome to the lifestyle!  If you are a competitve person then you need to know you are hooked already.

I think you'll find triathlon a punishing sport if you're not even motivated before you've even started it.
