Yes.

No. WP uses the mysql library. However, this talks to MySQL 5 just fine, AFAIK.

Not in general, no, but in specific some people have issues during
upgrades if they set their collation to the wrong thing. This could be
fixed by converting their database, but in general it's simpler to
just tell them to remove the collation setting in wp-config.php.

WP itself runs fine under PHP 5, and more and more plugins are
requiring it nowadays.

PHP 4 is dead. It just has not stopped thrashing yet.
