On #1, I really can't say unless you host is very restrictive on modules, and runs an old (Pre-5) version of Perl. UGH!

On #2, Unless you're testing CGI scripts, I would let the server set them. If you are, I'd pull mhttpd or something similar (aka a light-weight web server) and install that to test your scripts on. Anything was tested on mhttpd.
