Okay, here is my thoughts.
Since this is the Newbie area you can assume, unless it is a site you can log into and go...most newbies including myself do not know of the mining software you refer to.
We are real dumb.
We need it spelled out for us. What mining software do we need and where is it.
I told you we were dumb.
*hoped I would have more people joining us!*
Haha, hey no problem!!! I love helping newbies out!!
Basically imho cgminer is the best. It depends on your knowledge base, but (FEEL FREE to correct, add or negate anything I say BTC world..) in my personal experience CGMiner is the best, and GUIMiner as the second.

Now with the CGMiner, to make it short and sweet. Browse to the directory you have extracted all the files from to using a command prompt, once there type in 'cgminer' without the ' ' and then it will guide you through the rest
Host: mine.btcminers.net:9332
User: bitcoinaddress <--- here in the command prompt you can copy and paste your address from your bitcoin client of choice, right click in the black and hit paste
Password: anything
Press enter.
There are additional settings/displays and what not with it, more extensive details listed in their forums. I would write them out, but that would just be completely redundant.
