idock can charge ur batt for u but it is connected to usb oso.. wad u need is a power adaptor for USB... it is a plug where u can plug into ur power supply. then use the same wire to attach to ur adaptor n whallaaaa charging wit power supply.
for casing got many types..

1)silicone
pro: durable, absorbs shocks, some hav full protection like the iskin which i am bulkin
cons: dust can stick and it adds some thickness

2)hard crystal case
pros : nice to see cos it is see thru, protect from scratches
cons : it plastic will get scratched up n then time to change another, the case cant absorb shock, the case is difficult to put on and might even sumtime scratch ur ipod

3)leather :
pros: nice to use, almost full protection frm scratches due the durable leather, slightly more expensive like the vaja cases, slight shock absorbtion, LOOK REAL COOL
cons : expensive, hard to navigate because u need to remove it frm the casing, sides are sumtimes exposed and might get scratched

4)film protector
pros : NAKED... lol... u can c thru them.. doesnt add thickness, give scratch protection especially the invinsible shield,
cons : no shock protection, not all surface covered, hard to put on
