Very new in this and I would appreciate your help to get started.

My very good friend will be busy with other stuff and willing to give me his 10GH scrypt miner rig and I thought I would start mining viacoin, this seems the best digital currency right now. I have zero experience in mining, would you let me know, should I set the Viacoin mining settings on the sgminer or the mining pool will take care of that and points to the viacoin blockchain? If the latest is the case and  if I don't use a mining pool then how can I make sure I am mining viacoin and not something else?
