Do aircraft increase or decrease thrust while in the air (other than landing or taking off)? If so, how do aircraft accomadate for the extra lift generated? In particular, I'm curious about aircraft that use afterburner...any help would be greatly appreciated.

Yes.

By modifying their angle of attack. There are also additional flight surfaces used in some cases e.g. flaps.

Alright, so let's say an aircraft goes into afterburner, does the aircraft use flaps to modify the angle of attack, or just to modify the lift coefficient?

And just to clarify, modifying the angle of attack is generally modifying which way the wing is pointing (with relation to the direction the aircraft itself is going)?

modern planes with computer controlled flight (FBW) automatically adapt to whatever condition the plane is. So if the pilot's stick is in the centred and level position the computer will fly the plane straight and level doing all the adjustment necessary to the control surfaces.
Older planes require manual adjustments from the pilot.

But yes.. a change in speed requires a change in plane attitude.
