Questions of a rookie!

[Thor]

Coordinated Strike: Can I move before make an attack against an adjacent model or not?
This may be a stupid question but I only read the rules and I don´t have any models or something else so far!

[Carcharoth]

Yup. Typically (for a militia captain) you would use your captain to activate a bunch of militia. The militia would then move into combat with your target, then your captain would finally move in, using coordinated strike and getting support from all the militia.

Supporting Models:

First book: "Starting with the defending player, each player has the opportunity to nominate one of his models......."

Chronicles of Anyaral: "During a melee combat, starting with the attacking player, each player has the opportunity......"

defending or attacking?

Haven't got the books to hand to check, but it think it's fair to say chronicles overrides anything contradictory in the previous books.

[Carcharoth]

I'll admit it's a rule we are fairly loose with, but I found it more natural for the attacker to declare what he's doing first. Hopefully that is consistent within chronicles...
As Paul said, if in doubt, chronicles should be the definitive point of reference, but it's always worth checking here if there is any doubt

Ok! Thanks!
