Serial devices and clock pin

Ok, so PS/2 input devices are I2C? And I'm going to be using an I2C LCD. So, because I'm not Rx and Tx, I don't need to worry about the baud rate because none of those are "serial". Right?

So I could just put all of the clock pins from seperate I2C devices into one pin on the arduino, right?

And if I use the Wire library, I can also combine all of the data from the Data pins into one pin, too. Correct?

Ya know what? Can someone just point me to some good material on how to make a multi-peripheral I2C and I'll take it from there?
