Ot workout guru advice needed on shaping up

Ok for starters i am 5'6" "yep short mfr" at about 147lbs..for the past 3-4 weeks i have beenrunning 3 miles a day for 5 days a week, and doing very light weights at my house because i dont have much free time to join a gym or anything so im doing what i can at home. I have a bench and a couple dumbbells. Here is all i do about 4 days a week.
a.bench 3 sets of 10 and bicep curl dumbells 3 sets of 10
or
b. 2 arm tricep extension 3 sets of 10 and seated shoulder press 3 sets if 10

i eat no junk food, drink nothing but water, eat 90% protein that is baked and the rest is just salads. I was eating very low calories but i upped them and now consuming roughly 1200-1500 calories a day.

Sooo The question is, am i doing enough to tell any difference? Im not fat by any means, but i carry my fat in the bell area. What can i do differently to increase burning fat and toning up. Again keep in mind i dont have time to join a gym, as a matter of fact i do my 3 mile run during my lunch break at work. I just do a quick weight workout when i gey home. What can i do to tone up more? Not trying to be a body builder or none of that crap.. tia

breakfast- protein bar
lunch- either a salad, or one baked chicken thigh
dinner-2 baked chicken thighs, handfull of ground turkey, some green veggies.
dessert- banana with about a teaspoon of peanut butter
