For sure replicate the WP, plugins, MySQL (/whatever), and PHP versions, before trying to import anything. Then you might need to open the exported *.sql in a text editor and search/replace base url to your local, and WordPress is a horrible fucking nightmare. Who knows, it might work.
Is PhpMyAdmin available on the host? Pretty indispensable for this sort of thing (IMO)
"It's basically OK" So leave it alone. Otherwise, chances are excellent you (William) will break it.
