Good suggestions, all. As someone mentioned, I think my biggest mistake on turn 1 was focusing on making a pocket around the Western portion of the map, rather than just pushing, pushing, pushing East.
If you make certain that you take control of the hexes of the supply railroad in the north and coming northeast from Brest-Litovsk with your motorized/panzer forces, then meet with both pincers at Minsk, isolate it and move on toward the eastern objectives, you will naturally form a large pocket of the entire western Soviet forces.
Move always the furthest away troops from the front, first and let them attack the closest russians to make up a path where your panzers can travel through without to much hinderance of enemy ZOCs. There is no reason to let the first echelon of troops take out the closest enemies. Save their movement points for later.
This is also key. Your frontline infantry can move the furthest, so save as many of their movement points as possible.
