S128240D Clarification

I'm using the S128240D in 4-wire serial mode (based on sample schematic on this site)  and receiving a blank screen with about ~3V bias on VLCD.  Could someone verify that the following are correct:

- Sample schematics seems to be based on 3V and x7 Boost circuit (21V?) I have notice on this forum talks about x6 instead @3V or 3.3V.
- Schematics also use 1uF capacitors.  Would 2uF or 2.2uF result in better performance?
- SPI setup: using 500khz clk (for testing), with MSB first, Second Edge Phase, and Falling Edge Lead.  Is this correct?

- #Reset line stays High during operation.
- XCS stays low during byte transmission and high in between.
- Init sequence from the sample code is correct?  (what magic numbers should delay1-3 be at?)  I've included beginning of my init code below.  The rest is the same as the stock sample.

Much thanks,
