You probably won't notice much difference between CopyMem060 and CMQ060 on a 68060. CopyMem060 is faster at small copies which are more common but it takes lots of them to be "noticeable". There is a speed chart as tested in the readme comparing CopyMem060 to CMQ060 and other patches ...
CopyMem040 is significantly faster than CMQ060 (there is no CMQ040) on a 68040. CopyMem040 is in the CopyMem archive.

No, it doesn't matter when the patch is started. The point of putting it early in the Startup-Sequence is too speed up booting as AmigaOS uses exec.library/CopyMem() often. It should work to drop CopyMem060 in the WBstartup drawer as well but it is started late in the boot process so won't potentially accelerate booting much. Starting by shell or double clicking is perfectly fine as well.
Many other programs benefit from CopyMem patches. The newest versions of AWeb use CopyMem() to render the background and the speed difference with the patch is noticeable on my system when scrolling quickly. Many other programs use CopyMem() but few use it enough to be "noticeable". Various tests will show a speedup though.
