Truth be told, I don't know if a bicep/tricep routine will REALLY help your arms grow to the size you want them... although, it won't hurt... here is what I would suggest.
1. Hit larger compound exercises such as barbell rows, squats, and deadlifts... these will not TARGET the biceps (rows might hit them harder) -- but they do give the body an overall pump that can definately make your body grow as a whole.
2. Get a band for your home use... everyday (except days before tri/bi workouts) do 3-4 sets of tricep pushdowns (hook the band on top of the door and push down) for about 25 reps ... get a nice pump and blood flow to the arm. You can also do the same for biceps (hooking the band under your foot) -- this will get blood flow into your arms and keep a good pump in them (without actually fatiguing them) all week. -- credit BFold for this tidbit.
3. When you DO hit arms, try to hit the heavy exercises... Close-grip bench press, Tate presses, JM's and French Curls -- for biceps, Barbell curls, Incline DB curls, and Preachers.
Give it some time, and eat enough food, and your arms will really grow.
