I would add:
1) figure out why aussie dude would dump the players he suggested --
2) i think the optimum squad size is 12 players; aussie's dumps would get you around there.
3) on the positive side, Houmoller could be a real good player. Make sure he gets plenty of training.
4) Learn how to manage game shape to maximize your players current skills.
5) You are selling out your arena. With the beginning of the month coming shortly, you may be able to safely raise ticket prices to increase revenues.
As with all advice: figure out the reasoning behind all these recommendations. Good luck.
