Hi and welcome.
The first thing I'd suggest is figuring out how many calories you need to be eating by reading this thread:
http://weight-loss.fitness.com/nutrition/40273-how-many-calories-should-i-eat.html
Then register for a free account on
FitDay - Free Weight Loss and Diet Journal or
Calorie Counter, Diet Tracking, Food Journal, Nutrition Facts at The Daily Plate and start to log your food. This will let you see how many calories you're eating and how your nutrition levels are breaking down. Once you know that, you'll be able to see more clearly where you can make adjustments, cut back, change your nutrition, etc.
The next thing I'd suggest is checking out the various sticky posts in the exercise area of the forum (
Weight Loss Through Exercise - Weight Loss Forum). There are some very good posts on exercise, both cardio/aerobic and on incorporating weight lifting into your exercise plans.
I'd also suggest starting a diary in the weight loss diary area (
Weight Loss Diary - Weight Loss Forum) as well as reading and participating in other diaries. This is a good way to make updates to your progress and to get support from others. It helps to find the diaries of people who have successfully lost weight (or are losing weight) and reading through them as well. Following the diaries of those who have been successful is both inspiring and informative.
Finally, I'd say you should read as much as you can of the posts on the board, especially anything that's marked "sticky". There is a ton of good information around here and a lot of times questions that new folks have has already been answered very thoroughly - so do take the time to look around and read.
Hope that helps you to get started.
