You are comfortable with your current weight.. but unfortunately the only way to lose extra abdominal fat is to keep losing. Unfortunately, many females lose weight in the lower half last, and gain it there first (myself included). Probably not what you want to hear. (sorry).
Not sure what you mean about your glutes.. if you are feeling you have weight to lose.. then same answer as above. But if you want to change shape of them, then only way to do that is to do squats and lunges and lift HEAVY. ie. You don't want to do a weight that you can lift more than 8 times.
I would recommend starting with barbell lunges
.. and move onto rear-foot elevated lunges
when you are ready (they are a bit harder).
For squats remember that the lower you squat, the more you will engage the glute muscle... but be safe and use proper form when doing them.. low squats make you more prone to back injury particularly when lifting heavy.
If you don't have a squat rack, then the leg press will have to do... just make sure you are getting a good range of motion so that you are engaging glutes along with hams and quads. Make sure to position your legs so your knees are not bending past your toes tho.
Reality is genetics play a big role too.. you won't be able to fight that.
You've made some amazing progress so far .. wtg!
