Ah, those are server settings of functions that you probably don't have. You didn't perhaps CHMOD anything to no writing for everyone? Does your server support htaccess. AskApache is usually pretty quick with answering on this forum, but maybe they're on holidays. You might want to try their own site, but there's not much going on their either it seems. Anyway, to me it seems that the plugin works alright, but you don't meet the requirements so you only get to see the initial checks. When I activate the plugin in most cases it isn't "failed" but "ok" and then I continue with the settings. So, try to light your candle at your host, since especially this one doesn't sound good:
[ FAILED ] .htaccess capability detection
There's nothing the plugin can do if it can't make/edit the htaccess.
