where and how you mount them is up to you, most people put them under the armrest as its hidden, easy to mount, and easy to access. Its not necessary though, the dynavin comes with a USB extension that you can simply run to the glove compartment.
For the ipod cord, on an E46 I prefer to run the cord to the area by the emergency brake boot, you can fold/tuck the wire down next to the ebrake when not in use and its pretty much invisible, but very accessible if you are plugging in a lot (like when using an iphone). You can then stick your phone in the cupholder.
