Firstly, thank you for your answer Mike, now i want to ask you something about the steps in your answer:

1. Ok.

2. I dont have an .htaccess file, but i do have a httpd.conf file that's in EasyPHP-5.3.8.0/conf_files
I've read that .htaccess and httpd.conf are not the same thing, but the first one is used when the admin cannot modify httpd.conf.
So, how do i have to proceed in my case?
For the engine/settings.php thank you, i didnt know that :)

3. You mean to export the database with phpMyAdmin to an sql file or a .gz file and then import it in the remote machine, right?

Thank you for your time ;)
