How can I get my outer bicep to grow more?

Yes you can and should target the outerhead
it IS somewhat independent of the main belly of the Bicep

Sure, if you need to...after you've bulked up to probably a minimum of 3.2 lbs of fairly lean mass per inch of height you have.

6 feet tall = 72" x 3.2 lbs = 230 lbs at 18% bodyfat, but preferably lower (so you can see your muscles, lol).
