It also depends on how many devices you have in that bus... I'll remember that Philips has some formulas to calculate resistor values. And don't forget series resistors from each device in bus; 100 - 150R fits most cases.

Oscillator programming
You can't program it unless you own special programmer. Normally oscillators are programmed at factory (large amounts) or by the distributor if you need small amounts and need them fast.

BGA designs
Most semiconductor manufactures has their own succestions to designing rules for BGA components. There is no general rules for BGA's. Take a look to Xilinx and Altera web sites. Both has very good application notes for PCB layout.

lcd programing
Those chips are used allmost everyone. Locate OEM LCD manufacturer webpage and confirm that they use those chips and download datasheets.
HD44105 is controller and HD44102 chips are drivers for LCD dots
What kind EL power you got? Do you use driver chip? If so use chip datasheets to find resistor/capasitor that controls boost voltage/EL driving frequency. That's the place where you should add control. I added NPC driver chip LDR to control brightness
