Dude u really need to do some reading....

Here try this for lights........ http://www.greenstream.co.uk/aboutlighting.htm

And this as a general guide - http://greenmanspage.com/guides/indoorv1.html

Read all of that ask ur questions later, that will save u and us lots of time, otherwise to give u a simple explanation on something we´ll need to cover a huge area of other issues that u also dont know...
