iPod 30 Pin Docking Port

If the iPod still charges with a regular charger cable - also 30 pins, then You could perhaps change the male part in the charger. Or buy a new charger.

Easier:

As you propose, a adapter cable to USB would work also. It is IMO easier to just buy a plug charger from 120V/AC to a USB female. They can just be plugged in a regular outlet.

(Same in case you have 220V outlets or a car cigarette lighter plug in the car)

These are very cheap. (see Ebay)

The 30 pin plug on the bottom of the ipod itself has male in/out pins that are broken off. the usb charger and cable are fine. I want to open up the ipod and solder a usb charger cable directly to the 30 pin ports circuit board. I know a ipod or I phone require a special circuir board between the usb and 30 pin plug on the charger cable I already have that part ready to go

I think the 5+v is #23...
