You have to drop the steering column also. There is another bolt that can only be accessed from the steering column side.

As far as the "ignition bezel and light ring", they are part of the lock cylinder, which when you depress the metal tab through the radio opening, you have to get a good grip around the ring and pull the lock cylinder out. You may need to use a screwdriver to break it loose, but be careful not to gouge your dash. Once you drop the steering column you should be able to get better access to get the park lock cable out. The switch is removed through the radio opening. You have to twist it to get it out.

to change the ignition put the key in and turn it to the on position from there examine around the ignition you should find a little hole or little button push it wiht a punch and pull out the ignition. Should not require to much force.

even if you do get it out and changed, you still will have to tow it to the dealer and reprogram the scurity system to match the new key

It requires some steering column disassembly, and if it is a telescopic column, some special tools. The airbag, steering wheel, and turn signal switch need to be removed, along with lower knee bolster and panel. The cylinder comes with wire leads that need to be fed down the column.
