I use ************ for tracking since i can get it on my phone so there's no excuses about tracking my food. I also like it because its one of the few places that has a grocery store I use. With sparkpeople, my calorie counter, weightwatchers, etc., i put in a name and it would never find what i'm looking for, and it was such a headache to have to manually put in each thing. Its worse because I like variety and I cook at home a lot so there's tons of stuff I have to add in anyway.
Just don't deprive yourself too much with your calories, for me 1500 is ok for about a week, then i find myself slipping up for a few days. Also if you're used to a high calorie diet cutting drastically might trigger some really powerful cravings. But little by little you'll learn what works for you and you'll get better at it.
