I have always been a fan of CalorieKing.com for looking up nutritional information. They also have a great desktop journaling program, but there is a one-time fee.
A client of mine turned me onto a great website that allows for interaction between friends (similar to Facebook) regarding their diet and exercise. myfitnesspal.com is a free website with a built-in food and exercise database for online journaling. Here's how it works:
Go to www.myfitnesspal.com
Sign up for a free account
Fill out the necessary blanks so that MFP can give you an appropriate calorie range.

The EF page can be found at www.myfitnesspal.com/ElevatedFitness go here, then add me as a friend. You can also search for friends under the community tab.
Search foods in the database or scan a barcode with your smartphone (mobile app must be installed).
Most importantly, go to Settings--> Diary Settings--> Diary Sharing --> Choose an option that you are most comfortable with. I have set mine to "friends only".
Aside from maintaining focus on your goals, investigating nutritional information can be pretty interesting (and disgusting at times). I recently realized that a salad I really enjoy at Applebee's has 1500 calories in a full-sized portion! Whoops! Take a peek at some of your favorite chain restaurants and see what you can do to change portion size (half for now, half in a take out box) or preparation (grilled v. "crispy") to stay within a safe nutritional range.
Before you turn into a calorie-counting nutcase, I encourage you to journal well, but be realistic. Get into a good place with your intake and and then take a break from journaling. If you feel like you might be falling of the wagon, hop back on the website and journal for a few days. Journaling is not only about accountability but educating yourself on what foods are out there that are or aren't for you.
Get cracking!
