Orange 3g is a network that is used to provide phone and internet in the UK. The SIM card you are going to need will vary with the phone you are using. Orange offers SIM cards with min plans for about $25. This price is for the SIM card used in the iPhone. If you have an iPhone 4 Orange also offers their micro SIM, which is smaller than a standard SIM for the same price

no, and there are different types of 3G, one would be UMTS for GSM phones.

You will have to contact Airtel to convert your 2G phone to 3G. The same sim card can be used for both 2G and 3G, so you will not need to change to a new card.
