At the end of the episode with Jack O'Neill and Daniel Jackson, on General O'Neill's shoulder there are two stars. That would signify that he is a Major General, one rank above a Brigadier General.
When Walter dials the gate near the end of the episode, the dialing sequence on the screen changes into a completely different chevron sequence once chevron seven is locked.
Prior: Your arrival here was foreseen.
Mitchell: No kidding. So you see the future, do you?
Prior: Lessons of days gone by teach us of what will come to pass.
Mitchell: I'm a bit of a history buff myself. Doesn't help me pick the lotto numbers, though. So. Where you from?
Prior: Where we come from and where we are going are all the same.
Mitchell: Oh, I getcha. Wherever you go, there you are. I think that's Buckaroo Banzai. Me, I'm from a little planet called Earth.
Mitchell: We can't seem to disconnect the stones or turn off the device.
Prior: It is the will of the Ori.
Mitchell: Figured you might say that. Sure there's nothing you can do? Odds are we'd be more receptive to those stories you want to tell. Call it a miracle if you want.
Prior: When Hanonea fell from above and learned to fly on the way down, that was a miracle.
Doci: Great holy armies shall be gathered and trained to fight all who embrace evil, in the name of the gods. Ships will be built to carry our warriors out among the stars, and we will spread Origin to all the unbelievers. The power of the Ori, will be felt far and wide and the wicked shall be vanquished.
Jack: See, that's one of the great things about being a general. You pretty much get to do whatever you want.
Mitchell: I suppose after you save the world seven or eight times...
Jack: Yeah, but who's counting, huh?
Mitchell: Teal'c. Actually, he mentions it quite often.
Daniel: This is bad.
Vala: Worse than being burned to death?

Vala offering fruit to Daniel
While they are discussing the "path to enlightenment", Vala takes a bite out of an apple then offers it to Daniel, who looks a little perturbed about it. In the Bible, Eve ate of the forbidden fruit and then offered it to Adam who also partook of it. They gained "the knowledge of good and evil" by doing so.
Mitchell: Oh, I get you – "Wherever you go, there you are." I think that's Buckaroo Banzai.
Mitchell specifically refers to the cult movie starring Peter Weller and John Lithgow.
