xdebug.dump.COOKIE=* will dump all cookies on each php
warning/notice/etc.

I really don't know what is the best one, but I listed a couple of
clients at http://xdebug.org/docs/remote . There is also a Google SoC
project under way that is implementing a cross-platform open source DBGp
client.

Zend's zend-extensions. They prohibit Xdebug from loading. memcache
should not conflict, but you're using an ancient PHP version (4.3). TO
see the full power of Xdebug you'd need atleast PHP 5.1.

It all depends on the task that you're doing. The suite of settings is
different whether you're just debugging while developing, tracing,
profiling or remote-debugging.
