Hey Westheim,
I think the most important things for Germany on turn 1 are:
1) Destroy all Soviet aircraft on their airfields by running over them with ground attacks....at least all those within 3 hexes of the border. Also be sure not to leave any of your airfields with planes on them unguarded if the Soviets might be able to overrun that hex with trapped forces.
2) Seize every possible bridgehead. This amounts to 3 for Romanians, 1 for AGC, 2 for AGN.
3) Figure out what you are going to do w/ Finland - either go for broke assaulting the Leningrad forts, or dig in to wait for the Germans arrive and build up before you start attacking. The Finns can get in trouble very quickly if you are not careful.
4) Aim your attacks to penetrate behind Soviet forces rather than just assaulting them head-on or pushing them around a lot - go for max encirclements.
5) Once all your moves are finished for the turn upgrade Infantry and either Light Tanks or Fighters with the huge amounts of supply reserves you start with.
Kills on turn 1 are not the most important thing - surrounding and getting bridgeheads is key.
Have fun
