Army Setup Questions

[das123]

Looking for some advice from the gurus please.

Company vs Squad?
Is it best to use all of the 5 slots for each commander and have many small squads or is it best to lump all the archers together in a large company, all the light infantry etc?

Spread Amongst Commanders?
I don't think troops get any direct benefit from their immediate commanders so is it best to split the troops up amongst the various commanders?
If a commander routs do his/her troops follow suit?

Using Cannon Fodder
I've tried using cannon fodder troops but I find they just get in the way of my veterans and thugs. They may take a few arrows for the team but I hate watching a decked-out thug hovering around behind the troops and not being able to use his shiny new weapons.

Using Trample Troops
Should elephants and other trample troops lead the army into battle, or should they 'hold and attack', or should they attack from the flanks?

Other Tips
What other things do you look for when setting up your army? Do you have a standard 'core' setup?

Thanks. Looking forward to reading your insights.
