Hello.
I have few question about the spell Blade Barrier.

Blade Barrier

School evocation [force]; Level cleric 6
CASTING

Casting Time 1 standard action
Components V, S
EFFECT

Range medium (100 ft. + 10 ft./level)
Effect wall of whirling blades up to 20 ft. long/level, or a ringed wall of whirling blades with a radius of up to 5 ft. per two levels; either form is 20 ft. high
Duration 1 min./level (D)
Saving Throw Reflex half or Reflex negates; see text; Spell Resistance yes

DESCRIPTION

An immobile, vertical curtain of whirling blades shaped of pure force springs into existence. Any creature passing through the wall takes 1d6 points of damage per caster level (maximum 15d6), with a Reflex save for half damage.

If you evoke the barrier so that it appears where creatures are, each creature takes damage as if passing through the wall. Each such creature can avoid the wall (ending up on the side of its choice) and thus take no damage by making a successful Reflex save.

A blade barrier provides cover (+4 bonus to AC, +2 bonus on Reflex saves) against attacks made through it.

1) Where Blade Barrier can be put? In the middle of squares or in line between squares?

2) If Blade Barrier can be put in the middle of squares, does standing in the square cause you damage?
in the spell description it's said

Any creature passing through the wall takes 1d6 points of damage per caster level

3) If I use Blade Barrier as a ringed wall around me, does the people attacking me get damage from the Blade Barrier?

3.5) In a ringed Blade Barrier, who get the cover bonus? the spellcaster only or everybody around the barrier too?

Thank you for all your respond!
