1. get the best dac you can afford. i use a non-usb dac. if this is for your critical listening room instead of just background music, i would look at dacs from : audio research, mark levinson, classe, bel canto, and there are others.
2. do some experimenting. some people might hear the difference and others might not.
3. if you want to use the ipod, you are pretty stuck with itunes. you also want to look at who provides the airport express options that others might not have. i like itunes myself.
4. a hard drive is a hard drive. if you are going to have a large repository of tunes and if you will be serving possible multiple macs/pc's in your house, i would look at raid network attached devices as an option.
5. i use it with good success. i also use an audio alchemy DTI device to clean up the jitter from the airport express toslink output, then i go into an external dac from the dti.
6. wired is already better if you can use it. i use wireless to an airport express device with good success. i use 802.11g, i wouldn't want to try this with anything less, 802.11n would be better.
7. your on it now.
