PCB,DIY USB Mobile Phone Charger. Shield to GND?
Typically the shield would be tied directly to ground, and there would be a ferrite on the 5V line.  A ferrite on the shield would filter out noise, and defeats the purpose of tying the shield to ground.

In my opinion you don't need ESD protection on the data lines since there is no data connection, however you should tie the data pins together as some devices won't draw power otherwise.
