i like apple, it's just that if the iphone keyboard is the same as the one on the ipod touch, then i'm screwed, because i can't type a coherent sentence on that thing.
For what it's worth I'm often surprised at just how accurate the iPhone (4) keyboard is - it's possible they may have improved it since the iPod you're using was developed. Head to a store and try one out (or ask a friend). For the most part the predictive/corrective text works well, however I'm not a thumb texter - I use one index finger...
As for employing it as your MP3 player, you can do, but while the headphones that come with the device include inbuilt compact controls (volume up/down, pause and skip) they're not great sounding. I prefer my old iPod nano for music and podcasts simply because I like being able to use the controls without having to take the device out of my pocket to see the "buttons".
