I have just ordered the 'Powersupport Anti-glare' screen protector and the incase leather folio to carry the iphone around. I do not think I need anything else for now. Perhaps a car charger might be a good idea, but not just yet.
Thanks for your help everyone!
Good choice going with the Anti-glare - you'll love not having to wipe fingerprints off of your screen all day. There is certainly a trade-off in screen clarity but I was more than willing to sacrifice it for less fingerprints. The anti-glare is almost totally smudge and fingerprint-proof.
