If all you want to use ZSH for is better completion, the configuration is pretty easy. Place this in your ~/.zshrc:
autoload -U zutil # [1]
autoload -U compinit # [2]
autoload -U complist # [3]
compinit
However, it's worth checking out all the other great features of the ZSH. The above example will give you a pretty plain prompt with good completion. If you don't want to fiddle with configurations, but want to see what ZSH can do for you, Google for "zshrc" and you will get some ready to use configurations to get started.
