That looks great to me, since local will restore the value even if handler exits due to an exception (die). My only concern would be threads. I don't know how Perl shares variables between threads, and I don't know how mod_perl works in a multi-threaded Apache.

By the way, you can save yourself some typing by using our. The following code is equivalent to your code, but saves you from typing "NS::" every time you reference these variables:

our (
    $IP_address,
    %params,
    %cookies
);

sub handler
{
    my $r = shift;

    local (
        $IP_address,
        %params,
        %cookies
    );

    .
    .
    $IP_address = $r->connection()->remote_ip();
    .
    .
}
