High protein and low carbs. You could get all fancy and get into keto but I've personally never liked it. Keep it clean and simple, if your losing 1-2lbs a week your doing good.
Definitely possible dependent on how long you've been training and where your at now. Lateral delts are a larger muscle group than biceps, and many people can put an inch on their biceps in a year.
Well, it's definitely doable. You'll stall right around 90-95lbs for a bit, you'll see what I mean. Once you hit 100 you'll get back on track. Currently warming up with 100s.
Not to burst your bubble, but I'd still consider you novice. I'm an inch taller than you, have twice the experience, almost an extra 40lbs on you (same bf%), and my lifts are a great deal more and I...

Lol TKD and Karate are near useless in a fight. BJJ is respectable, but at 124lbs you shouldn't be taking ANYONE to the ground. Last time I grappled against a kid your size I curled him into a ball...
