When I light up the fireplace, the room is filling up with smoke.
I've checked the flue and it's definitely opened as far as it can go.
What I'm wondering is, is it possible that the chimney, or the pipe
leading up to the roof, is partially clogged?

Sure. Could be a bird nest in there, for example.

I've heard others
mention too that it could be due to the air flow outside, causing the
smoke to drift inside the house.

That could be too. But less likely than an obstruction.


Also, the fireplace has what appear to be transparent doors on it (I'm
guessing they're glass, but not sure). Is it safe to close these
doors while the fireplace is lit? I just didn't want pressure to
build up or something weird to happen.

Yes, it's safe.


If the chimney/flue/pipe (whatever it's technical name is) is clogged,
what are the solutions? I've heard something about special logs you
can get for the fireplace that help clean out the pipe, do these help?
What do I need to repair this?

Those "special logs" are intended to help remove soot, and they really don't
do such a great job. The best thing to do is to hire a chimney sweep to
professionally clean your chimney. Make sure to tell the sweep about the
problem, and ask him to check for possible causes.
