HTC Pro question regarding listening to music

[Troyicus]

I pick up my HTC Touch Pro this Tuesday. Yeah me. After doing some reading on it, I am confused regarding listening to music. I plan on using my phone to listen to music while I work out. What I need to know is can I buy some stereo headphones that plug directly into the usb spot or should I buy the usb adapter that has the 3.5mm end on it with a mic. I have included two links on what I am looking at. Which one should I get?

Again I want to have one cable so I can listen to music but also use the cable to answer phone calls.

Also can I use my HTC Mogul car charger on my HTC Touch Pro?

Thanks for any help given.
