Worf was supposed to have been visiting his parents on Earth, but that was before Kira Yoshi got transplanted into Kira. This may have altered the time table a little bit. I suppose it's possible that the Defiant was at Earth for some reason when the Borg attacked so off they went to the Typhon Sector to help intercept them.
Or Worf's visit home and the Defiant's presence at the battle could be two totally unrelated incidents:
"Hello Capatain, I'm back from Earth." "Mr. Worf, get your ass back on the Defiant. The Borg are about to attack Earth..."
Personally, I think the Defiant was already doing something close to Earth. Doesn't it take at least a few days to get there from DS9? The Borg have never been ones to send out invitations for the battles.

Maybe not now, but he has been in the past a very proficient helmsman. And again, we've seen him at the Defiant's helm on a few occasions I'm thinkin'.
The Defiant could've been at Earth, and ordered from there to go to the Typhon Expanse and fight the Borg. Worf's line when he learns Keiko is pregnant again does seem to indicate he plans on being far far FAR away when that happens ...

I'm not sure if O'Brien is an ace pilot or not, but he does have plenty of experience. His main fields of training may have been infantryman cum transporter chief cum starship/station chief engineer, but he flew plenty of missions piloting those runabouts...
I don't think he piloted the Defiant more than once, though ("Rules of Engagement"). It is a weird job for the engineer of the ship to be doing. Perhaps O'Brien had come to the bridge to give Worf a report on the progress with intercom repairs ("Still not working, sir, and the commbadges are all low on power now - so please meet Christina. She knows her way down to Engineering if you need me again. Just attach this message scroll to her leg and..."), and the Klingons chose exactly that moment to strike. And since the poor regular helmsman was sitting right next to a console... I guess O'Brien was the most practical replacement in the heat of the moment.
