I use M-x customize, I'm told to add these lines to .emacs

(autoload ’gp-mode "pari" nil t)
(autoload ’gp-script-mode "pari" nil t)
(autoload ’gp "pari" nil t)
(autoload ’gpman "pari" nil t)
(setq auto-mode-alist
   (cons ’("\\.gp$" . gp-script-mode) auto-mode-alist))

When customizing your Emacs you don't need to add anything to .emacs because in the customize buffers you press the button to save your customization for further use and Emacs does all for you.

If you need to add the lines above to .emacs then just do it! Usually any place is good outside the customize clauses. It's good too to add them in a "block," with empty lines before and afterwards and a comment for what and why (and when ?) they were added. If you add more than one cons to auto-mode-alist you can merge them together. It was said on this list that \\' is a more precise description of a file name's end than $. When using more excessively the regular expressions the code can become very hard to understand:

(setq auto-mode-alist
   '(("\\.\\(xsl\\|id\\[de\\]\\)\\'"                 . sgml-mode)
     ("\\.\\(plist\\|xml\\|xsl\\|fo\\)\\'"           . xml-mode)
     ("\\.\\(tgz\\|tar\\.\\(bz2\\|gz\\|Z\\)\\)\\'"   . tar-mode)
     ("\\.\\(arc\\|jar\\|lzh\\|zip\\|zoo\\)\\'"      . tar-mode)
