I am using Apple lossless format on my 40gb and think it should hold approx 1,700 tunes or so. You can always move songs/artists/etc to and from your computer, which is nice as well.
I tried the Shure e3c's and were not impressed. I will be honest, I didn't give them the week, nor did I need to. When you insert them into your ear and you get the "suction" to block out exterior noise it also "plugs" your ear. As in the same feeling/sound as when you are underwater. Also, when you swallow, walk, etc. you hear your bodily noises. Not too audiophile to me, at least not for the $$$.
I bought the Grado SR325's and have only been smiling since. They are NOT noise cancelling, so you will have to determine what is better for you. However, I travel and often find myself in a hotel room at night, these are simply awesome, yet still allow you to hear if the phone rings, etc.
