I had the same problem you have now when I wrote my thesis, but I didn't use any of the packages you've mentioned (probably they didn't even exist since it happened many years ago).
But I read this beatiful introduction to the LaTeX world (it is written in Italian!): Una (mica tanto) breve introduzione a LATEX2ε that helped me much.
At page 77 (93 of 109) you can find a description of the parameters relative to page layout:
.
If, for example, you want to reduce the parameter no. 2 of 1/2 inch you have to give a negative value to \voffset in this way:
\setlength{\voffset}{-0.5in}
But this is a very old manner to deal with these things. Nowadays packages like frontespizio (if you learn how to use them) will reduce much your work.
Anyway it has been nice to remember the days of my thesis.
Tanti auguri per la tua laurea!
BTW: I used the titlepage environment for that...
EDIT
Despite you have already accepted an answer, this is my old code (1998) adapted to your frontispiece:
\documentclass[11pt,a4paper]{report}
\usepackage[english,italian]{babel}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{times}
\usepackage{graphicx}
\setlength{\voffset}{-0.5in}
\setlength{\topmargin}{-0.2in}
\setlength{\textheight}{240mm}
\setlength{\textwidth}{142mm}
\setlength{\evensidemargin}{0.3in}
\setlength{\oddsidemargin}{0.3in}
\begin{document}
\begin{titlepage}

and this is the result:

Tanti auguri di nuovo!
frontespizio, I can only recommend it. ;-) – egreg Jun 22 '13 at 18:57onlyincludeoption, you can use a PDF file built with other tools. – egreg Jun 22 '13 at 19:09
