I guess you are using Windows? In that case, not from Sun - they only have an installer executable available.
About copying the JDK directory to another machine: This should work in principle, because everything that the JDK needs is in the directory where you installed it, however the normal installer also sets some things in the Windows registry. The browser plug-in won't be installed if you just copy the JDK directory. You can just try it and see if it works.
