Makes me sad that I never got a chance to go down to Holloman AFB to see the F-22s before they left to Tyndall AFB in April 2014.

F-22s at the 2008 Wings Over Pittsburgh airshow:

And 2008 Oceana:

In the first pic, are the intakes blocked off, or is it some trick of the light?

I think it's condensation inside the intake. The Russians use a system that closes off the intakes in the front and pulls air in from above in order to avoid FOD in the engine on takeoff. I don't think the Raptor has such a system, nor do I think they could take off from an unimproved runway if they wanted to.

I think the raptor does have what looks like vents on the top of the fuselage, though for what purpose I don't know. You can kind of see the jagged outlines here

I would guess that there is some system that can regulate the flow of air into the intakes, particularly at high speed. Perhaps some sort of bypass? No idea, really. I'll have to look into it.

A high-fidelity aeronautical simulation (Ace Combat 5) tells me it opens when the afterburners engage.

I believe the center opening is for refueling as a boom sticking out the front would increase its radar signature.

The front fans of a turbine are a major radar reflector, so the F-22 uses curved ducts to hide them. The B-2 and F-35 do the same thing.

Yep, and the gun is beneath a door on the right wing root:

Not the refueling port, there are two sets of slats on either side. They're closed in that photo, but you can see the outlines.
