Alright, to answer your questions:
1. I'm 14, and will probably watching it on my computer in the family room, so I guess nothing way too mature (though I can handle mature-er plots, concepts, etc.)
2. I like watching sci-fi action and have recently developed an interest in Twin Peaks.
3. Quality isn't an issue. I used to watch edd ed'n eddy (back around when I watched Toonami)
4. I would like to try some mecha and maybe some of the more comedy-focused stuff
Also, if you can tell me what's available on Netflix instant, that'd be great. I really love the service, and my PC's dvd player might have some issues.
