Push ups don't work your biceps. Biceps are a 'pull' muscle that work with your back muscles in exercises like rowing and chin ups.
They work your pectoralis major (chest), triceps and anterior deltoids.
Good tricep exercises:
push downs on a cable machine
kick backs with a dumbbell
dips on a bench - or sometimes gyms have machines for this.
Otherwise, an overall fat reduction would get the 'arm flab' down, since you can't spot reduce, only strengthen the muscle underneath.
