What can I delete to restore space?

[macswitcha2]

I will like to know what is safe to delete when trying to restore space other than unwanted apps and pics.

Is there site with a list of things that are safe to delete in OS X lion?

For instance, is the bin/zsh something that is safe to delete?

One idea

Search the app store for "Disk Diet", it works fairly well at cleaning up temp / cache / unneeded files.
