Streaming music and audiobooks from a NAS with an MP3 Player via WLAN

[Attreides]

I have a lot of digitally bought music and audiobooks. Recently I thought about buying an Ipod classic to throw everything on it, so that I have acess to my entire libary without having the loud PC running and getting on my nerves all the time. I know it's from apple, but in Germany it's the only player being bigger then 32 GB. But I need a new external harddisk too, to store various data on it, including my music collection. The best would be a NAS with a minimum of 2TB, the more the better (4-8 TB would be NICE).
So what about just accessing the music libary on the NAS via WLAN? Is there a non-Apple device that can do it? Maybe even internet (has to have flash then), to acess AbI, roccatune, imeem, last.fm and the rest of these wonderfull sites? Sending listened tracks to last.fm would be nice too^^

I know, this one is hard^^
