Yes.

Yes and no. Normally yes. But depends a bit on the rest of the
`.emacs' file: sometimes, badly written code can override (or
conflict) with other declarations elsewhere.

In fact, this message is quite clear: Emacs does not find the
file `screen-lines(.el)', as requested by the `require' command.

So, in order to get that chunk of code working, you need to
download the package `screen-lines.el' and put that file into
a directory that's in your load-path (same directory as your
`.emacs' file would do, for example).

Get the package from there:
