Marzutra, are you sure you have to disconnect the CRT? In many older sets the CRT is mounted to the metal chassis and everything is removable in one piece.
From the looks of you pictures, I think your CRT has the type of base shown in my second picture. That is the newer design. The plastic piece can come loose without damaging the tube pin connection, so you may not have a serious problem.
EDIT: Just read what you posted while I did. Never mind this part.
Standard warning, be very careful around the CRT neck (where the base and yoke are). There is 14.5 lbs per square inch atmospheric pressure on the glass. That's about a ton per square foot. The tube could implode if the glass breaks and you could get a face full of glass shards! A pair of goggles would be a good idea. The front glass on the cabinet is called the safety glass for a reason. The CRT glass is thicker towards the front of the CRT, but that makes it heavier than you might think.
TVs are more dangerous to work on than radios because of the CRT and the higher voltages used. I'm not sure getting into this is a good idea if you are also moving at the same time.
