You only need 3 exercises per session, something like this:
MONDAY: LOWER (SQUAT), PUSH (OVERHEAD PRESS), PULL (ROW)
WEDNESDAY: LOWER (SQUAT), PUSH (INCLINE BENCH PRESS), PULL (PULLUP/PULLDOWN)
FRIDAY: LOWER (SQUAT), PUSH (OVERHEAD PRESS), PULL (DEADLIFT/CLEAN)
You can add a couple of sets of 10-12 reps a one or two specialty exercises at the end of each session, like calf raises, situps, curls, triceps extensions if you want, but they are not necessary to have a well balanced program you can make good gains on for a quite a while. Google Bill Stars 5x5 or Rippletoes 5/3/1 for more ideas and details.
