Not that I want to discourage you from mining but with an NVIDIA card you would be better off looking at scrypt coins like Litecoins, Feathercoins, Digitalcoins or something along that line, the reason I say this is I started the same place you are back in August and over 3+ months of mining on BTC on a very similar card as yours and 11 block erupters I only had .5 BTC and an increased power bill.
I have updated my hardware to ATI cards and am working on different scrypt coins and doing a decent profit after electrical and the cost of the cards.
The app I use for mining is cgminer 3.7 which I run from the command line (http://ck.kolivas.org/apps/cgminer/)
If you are looking for a GUI application I would check out guiminer (http://guiminer.org/)
Again if you are just wanting to do BTC just for fun and see what its like you will probably do a couple of cents a day in BTC but if you are looking to make decent money on it your not going to with the hardware you currently have.
