I've made a photoshop project of the usb port replacement basing of this thread, 3 little questions please:

1) Is that right this soldering project? Can it be an usb-port for daily use by reassembling gently the N900?

2) the SHIELD attachment of the usb port where should be soldered?

3) where should be soldered the second pin from the left?

EDIT: Can someone give me the link to a good soldering iron capable of doing this other solution:
