I’ve allways done my mt installs via FTP. Just upload the files in exactly the same directory structure that the archive is in. If you want it in a sub-directory, create that, and upload the same way.
the default path to perl is correct in all your files - you’ve just got to edit mt.cfg properly, and db-pass for the mysql database. in the config files, make sure you specify the mysql host name - local host won’t work. Aside from that it should be easy.
