Topical Acne Treatment for Oily Asian Skin

I'm an Asian female, with oily skin. I have pitted acne scarring on my cheeks and I'm looking into Fraxel laser. For the time being, I'm trying to get my acne under control.
My skin looks congested, but I only have a few big pimples on my chin. Please give me some recommendation on what type of topical gel and oral antibiotics would help me. Please tell me the difference between Tazorac and Retin-A. Which one works better for my condition and is gel better than cream? I have bought a LED blue and red light for my acne treatment. Is it appropriate to use topical gel in conjunction with LED light? I want to start on oral antibiotics or antifungal for acne. Please recommend me one that is most tolerable. I heard Spironactalone helps with acne too, should I try it?
