For a beginner, I see no reason to specifically target little muscles like biceps/triceps/forearms. Pull-ups/dips/deadlifts should hit those muscle groups sufficiently. I would focus on 5-6 different lifts to start. Deadlifts, squats and bench are the big ones. I also suggest overhead presses, pull-ups and dips. I suggest a 2-day split of DL/OPs/PUPs and Squat/bench/dips. People will quibble with things, but don't neglect the big, compound lifts in favor of dinky...
