(If you can shoot a person with a gun, or attack them with a sword, using your astral perception, you can cast a spell at them as well... obviously Astral Perception allows targeting physical objects, or the physical actions would be impossible all together)
That seems like a horrid analogy. You can fire a gun at something, thus you can cast a spell at them? To fire a gun you just need to point in the right direction and bang, you shoot them. You can use a computer to aim and fire a gun, but you cannot use a computer to target a spell, so your analogy obviously falls through very quickly.
Yes, you can tell that someone or something is in a particular place, and thus you can make physical actions towards those things. In order to cast a spell however, you must be able to
see what you are targeting, and while viewing things astrally you don't see
anything on the physical plane, you see an astral shadow of it on the astral plane. So, firing a gun works because you can go 'I want to shoot at something at roughly that spot', but casting a spell doesn't because you can't go 'I want to target that spot but on the physical plane' because you must see something to target it, and you cannot see the physical plane. It'd be like targeting someone through their shadow. You
know they are there, that they are connected to their shadow, but you still can't target them with a spell, because you can't see the
actual target.
As for blind being a -6 penalty, should point out that total darkness is also only a -6 penalty, and in that case it is physically impossible to see anything as well. I'm not sure why exactly the devs simply imposed a -6 penalty as opposed to making it impossible to see something when you are blind (I'm supposing that the quality refers to actually blind as opposed to 'legally' blind). This means it is technically possible though difficult for a blind mage to target stuff with their natural LoS (despite being blind), but they would need a perception check (at -6) to locate the target in the first place, and then casting the spell would also be at a -6. Seems a little 'cheap' to me, though the penalties are hefty, it doesn't exactly make the character all that blind. That's more like 'needs to wear glasses'.

Not quite the same thing. A blind mage using Astral Perception still has a physical component which is why he could (IMO) target something on the physical plane.
You're very right, they can target something on the physical plane, but the problem is that the distinction is never made of what form of targeting, because a target can be acquired through touch as well. It says they can cast a physical spell at a target, but never that a target can (or can't) be obtained through astral sight.
P.S. I think indirect physical combat spells might work, as those don't require a target, simply that the mage form up the spell and throw it in some direction, as opposed to causing an affect at a particular point (like powerbolt for instance). I'll have to look that up a bit more.
