The less you have to lose, the longer it will take. With only 10 lbs to go, at most you can expect about .25 - .3 lbs per week.
Variety is the spice of life. It doesn't really matter whether you do time/distance or intensity; it's more about the total calories burn. Higher intensity is usually better, since it means less time spent doing something, and has the same benefit as burning the same amount of calories over a longer period of time.
Don't worry about the "fat burning zone" or any such nonsense either; just focus on doing what you enjoy. Place emphasis on strength training, as that will boost your metabolism and improve the appearance of the fat you do have.
It will take time. It sounds to me like you're right on track. Just remember that this isn't the biggest loser, and those kinds of results aren't typical. It'll take time to take it off!
