I have similar goals - last week I lost 5 pounds. I make sure I count EVERYTHING I put in my mouth and stay towards the lower end of my calorie range (but not below it) and make sure I do cardio every day, no exceptions. Although, if you need a rest day, by all means take it to avoid injury. Also, I never eat within 3 hours of bedtime. And get plenty or rest so you have energy to put in a good hard workout the next day!
I've been doing either 60 minutes on the elliptical, or 30 minutes running/30 minutes elliptical, so basically, 60 minutes high-intensity cardio. And when I'm on the elliptical I'm not reading or watching TV - I've got a high amount of resistance set on the machine and I'm putting in all the effort I can muster. Make sure you stay hydrated, because being hydrated is not only awful for your health, but can make you gain weight through water retention. When your body thinks it's not going to get enough water it holds onto what water it does have.
10 pounds or more is totally do-able at the beginning of your weight loss because you have that much more weight to lose, but it will not be as realistic after you've lost quite a bit.
