For Iphone 2G - which one is better Firmware 2.2.1 OR Firmware 3.0?
I am new to it so don't know in which version the applications help more. So please tell to which version I should upgrade?

I'd suggest upgrading to 3.0.2 because some applications won't work on 2.2.1

3.1.2. Unless you downloaded anything else manually this is your only option

The latest version is usually the best route.
