If your fat do you have to lose fat before adding muscle

What are you planning on eating with only 30 g's of protein a day?  Protein is very important to build muscle.  You need more then 30 g's a day.  Just work out and eat 5 small meals a day and cut out the junk and you will do fine.  It just takes time and dedication. 

You need to exercise first before you concern yourself with lifting weights to gain muscle mass in the arms.

Obviously you dont want to become a stick and then try and build mass again, but until you're the proper weight (on the high end of the scale) I would say just worry about diet and exercise right now.

 Perfect.  Get a good cardio sweat up then lift weights you keep burning fat for the whole workout.
