You need money before you can buy items, and enough money to afford the items the NPC vendors offer.
You can buy a Minishark from the ArmsDealer once you have a Musket obtained from the Corruption's Shadow Orbs. He sells it for 35 gold.
There are no main server on terraria so I would suggest google searching "terraria servers" and see what comes up. I have done this and been on multiplayer.
The downloadable Program and gaming network Steam is a good place to buy Terraria, although it is coming to console soon.
They might be hamachi run.
steam/many many others, just type terraria download
You can buy it through Steam, TerrariaOnline, etc. Just go onto Google and type the keywords "Terraria" or "Get Terraria", and go from there.

They dont sell it anymore. You should buy Minecraft instead
It will depend on the format that you choose to play the games. Many people prefer the iPhone over the iPod to play games. Both games, junk Jack and terraria, are both popular games.
