Questions - tail light replacement and strut mounts

Hi,

Have general questions regarding 2 topics.

Have a bulb that is blown in right handside tail light cluster. Have looked at replacing the bulb but cannot get inside the unit at all. How do you change bulbs in the tail light cluster?

On the rear right hand side have a noisy strut, has been diagnosed as possible strut mount. Struts were replaced about 3000 miles ago by previous owner. Has anyone changed the strut mounts themselves, and how big a job is it? Any recommendations on whether to go with manufacturer mounts or change to a performance mount.

Thanks,
