I would evaluate what you are doing now, and try to tweak it a bit to see if you can lose more. Just make sure you feel comfortable in your lifestyle now before you tweak it up a bit. You don't want to feel overwhelmed.
I was in the same dilemma, lost weight, but wanted to get the final 10 off, so I started counting my calories on my work days. I found ways to cut calories back a bit and amped up my cardio a few more minutes. It took 5 months but I hit my goal of 125lbs. finally.
Try a new sport, measure your food to make sure you aren't over doing the coffee creamer or butter, etc. It seems like a pain, but it's worth the effort, and eventually it becomes second nature to know how much calories is in 2 tablespoons of creamer ( just an example). Good luck
