On the requirements page, it notes you need PHP5+ (5.2 recommended), MySQL 4.1+ with InnoDB, and points out PHP safe mode should be off. FTP is also needed(duh) and the page also suggests GD Image Library and allow_url_fopen set to ON. At least 500MB should be enough space, and as for bandwidth, don't let 43728907893GB trick you. When there's a lot of bandwidth/space, it usually lacks features.
