Yes. But you need to ask your provider to load your two lines onto one SIM card. This depends on the operator. i.e., not all operators provide such SIM cards.
If they do, under settings/phone you will have a section called "SIM applications", where you can switch from one line to other.
Two lines cannot be active at the same time. But you can forward incoming calls of one line to the other. In this case incoming calls coming to both of your lines will reach you, but you will only be able to make calls from your "active" line.

Yes and no. The iPod Touch has almost the same features as the iPhone. The iPhone just have 3G, SMS, Phone etc.
No, the only phone with higher quality is the iPhone 3G[S], and the new iPhone that isn't out for you yet.
Multitasking does not work on a iPhone 3G, You must Jailbreak your Phone to do that (Beaware that your phone would be very slow with Multitasking)

The iPhone 3G is capable of accessing a 3G network. Some of the older iPhones and the new iPhone 4 can not access a 3G network, however. There are many droid that have the same applications as the iPhone but that will hook up to the 3G network.
