Though I am technically going to be manifesting a psionic power, the mechanics, I believe, are the same. So I thought I'd ask regarding magic as it is more familiar to most.

So, you need line of effect rather than line of sight for most spells. What does that mean regarding targetting? If, say, I had blindsight 60', but had no actual sight (blindfold of true darkness), would it be possible to target a creature outside of that range? I know how I can ascertain their square (feat in Complete Adventurer, or have an ally call our their location), but can I/how can I target them? If anyone can reference rules to this that'd be even more helpful, or even just the generally agreed upon method of handling this.

Edit: Oh, and area of effect spells aren't much of an option (telepath).

Target or Targets: Some spells have a target or targets. You cast these spells on creatures or objects, as defined by the spell itself. You must be able to see or touch the target, and you must specifically choose that target. You do not have to select your target until you finish casting the spell.

BLINDSIGHT AND BLINDSENSE
Some creatures have blindsight, the extraordinary ability to use a nonvisual sense (or a combination of such senses) to operate effectively without vision. Such sense may include sensitivity to vibrations, acute scent, keen hearing, or echolocation. This ability makes invisibility and concealment (even magical darkness) irrelevant to the creature (though it still can’t see ethereal creatures). This ability operates out to a range specified in the creature description.
• Blindsight never allows a creature to distinguish color or visual contrast. A creature cannot read with blindsight.
• Blindsight does not subject a creature to gaze attacks (even though darkvision does).
• Blinding attacks do not penalize creatures using blindsight.
• Deafening attacks thwart blindsight if it relies on hearing.
• Blindsight works underwater but not in a vacuum.
• Blindsight negates displacement and blur effects.
Blindsense: Other creatures have blindsense, a lesser ability that lets the creature notice things it cannot see, but without the precision of blindsight. The creature with blindsense usually does not need to make Spot or Listen checks to notice and locate creatures within range of its blindsense ability, provided that it has line of effect to that creature. Any opponent the creature cannot see has total concealment (50% miss chance) against the creature with blindsense, and the blindsensing creature still has the normal miss chance when attacking foes that have concealment. Visibility still affects the movement of a creature with blindsense. A creature with blindsense is still denied its Dexterity bonus to Armor Class against attacks from creatures it cannot see.

A creature with blindsight 60' could only cast spells on targets with the target of specific creatures at a maximum range of 60' regardless of whether he knows they are there or not because he cannot see the target. If the character can also see in another mode other than blindsight, he still sees it thus can specify it as a target. A blind creature with no modes of "seeing" could never use a spell that "Targets" anything other than what he can touch (which includes himself)

A creature that is blind, and using blindsense, simply knows the target is there, but does not see it.

You still can use spells (and powers) that use the Effect, Area, and Line of Effect modes of targetting, even if you cannot see the location you specify.
