I agree with TMony. Read the stickies. They will give you a lot of info and if you still have questions please post.
Gotta agree with this also, the stickies are a good source of info, including cycling also, as whiskers said dont hesitate to ask questions it can be a pain trying to find things using the search function.
Personally I wouldnt add fish until it was fully cycled.. see the fishless cycle section in the link kissyboots provided for you. I, much like Kissyboots, didnt cycle my first tank and I didnt even check the water params all that much, I found a site that said add fish wait a month and then change the water so thats what I did, it actually worked for me but I wouldnt recommend it. Now I use media from other tanks.
Welcome to the tank..
