Actually you can. When I had my iPod Touch, I had a standard headphone jack much like the one on our tablets. I got a headphone with a built in microphone from one of my older phones and I was able to make calls, receive, listen, and talk through the headset and my iPod through VOIP. I forgot there was a built in microphone though so you might be able to do it without this headset.
As for 3G, I heard that all you do is take your device into your desired carrier or call them and have it activated somehow. Explain that you have a tablet you bought and want to activate it with their service and they'll ask you questions such as serial numbers, model number, etc.
I read somewhere on the net about hacking the tablet and receiving free 3G service from all over. If you do a quick Google search, it might come up.
