Units deploying to Afghanistan began receiving them in April 2010, IIRC. Special Forces and other select units had been acquiring them for some time prior to that.

The combat action badge are worn with "Class A" Army green, blue or white uniform coats. You must wear that uniform when wearing the badge.
Yes, the multicam uniform is authorized for wear by the 82nd Airborne Division in the U.S. Army. The multicam pattern is now the standard combat uniform for the Army and is widely used by various units, including the 82nd Airborne Division.
The U.S. Army started issuing the Multicam Army Combat Uniform (ACU) to soldiers deploying to Afghanistan in July 2010. The Multicam pattern was chosen as it provides better camouflage effectiveness in the Afghan terrain compared to the prior Universal Camouflage Pattern (UCP). The use of Multicam ACU aimed to enhance the soldiers' combat effectiveness in the specific environment.

Earned awards can be worn on the service uniform. You will have to consult the appropriate regulations for placement, they are typically going to be lower priority of any Army issued awards.
I went through Basic in 98, and the Class A uniform was the current Army Green uniform, which is in the process of being phased out. At that time, everyone was issued Class A and B uniforms. A lot has changed in the 12 years since, but that's one which isn't likely to, and you should still be issued the current Army Service Uniform (which replaced the Class A/Army Green uniform). Upon graduation, you would be wearing that uniform for the graduation ceremony, and thus would have to have one issued to you. Special uniforms, such as Mess Dress, however, will have to be purchased on your own, if you wish/need to have them.
They wear the same uniforms as the rest of their unit. This may be the ACU or MultiCam uniform for the Army, the MARPAT uniform for the Marines, the ABU for the Air Force.... special operations units have a bit more leniency in what they wear as far as uniforms go. They might wear any of the above, or even the phased out BDU, DCU, or ERDL uniforms if they saw fit to.
It is the Army branch of the military that issues green socks as part of the uniform. Other branches issue other colors of socks. The green is consistent with the rest of the typical green uniform issued to Army personnel.
The digital Universal Camouflage Pattern (UCP) is the norm, but units deploying to Afghanistan are being issued MultiCam. Special operations units still have the option to use M81 woodland or the three color desert camo when they feel it appropriate to do such.
Because it's worn uniformly by all personnel in the Army.
The uniform was first fielded in April of 2005
There is no flag on the dress uniform
