Wheel build help

Bonjour,

I am about to lace my first wheel set. Velocity deep v + Dura-Ace 7600 hubs.
There is a spoke length calculator here http://www.bikeschool.com/spokes/

I have these measurement so far:
wheel size: 700c

• Effective Rim Diameter (ERD): 582
  
• Hub flange diamter: 120 front and 100 rear
  
• Number of spokes in the wheel: 36
  Are these good? Something tells me I am completly wrong...
  
  

I miss these:

• Hub Center to Flange Center. What is that?
  
• Hub Spoke Hole Diameter. Not sure to be precise enough.
  
• Cross Pattern. What is the most common cross pattern?
  Do you know about those measurements?
  
  

Help on that would be very much appreciated!
