TLC5949: TLC5949

Dear Sir or Madam,
Regarding TLC5949,I have a few questions:

1-Suppose we want to use "multiple daisy-chained TLC5949s" in our project(based on the figure of page 1 of the datasheet) .Imagine total number of these chips, is: 10 .
Also,we want to use "Display Timing Reset Function"(mentioned in page:26) .

It seems reasonabe to send Control data before "GS data write". Is it true?
In this case: SCLK,LAT,GSCLK are common between all TLC5949s . At first,we have to apply zero logic(0 V) to LAT,then send "Control Data" of 10'th chip,then Control data of 9'th chip,till control data of the first chip(Figure:11 of page :12) . After finishing "Control data" of the first chip,we have to apply logic one(3.3 V) to the LAT signal .
Is it the right method for sending "Control Data" to these chips?If we don't want to change the control data,can we use the above process only one time?

2-Can we use the same method(mentioned above) for "GS data write"(based on figure:9-page:10)?
Just after sending "GS data write" of the first chip,we need to apply 4096 clock pulses as GSCLK and we don't need to apply GSCLK continuously?Is it right?
If "GS data" for all chips are variable during the time,can we use this method repeatedly without sending control data?(**Remember :control data are NOT variable,and I presume that we sent them once only as mentioned at the end of question 1**)

3-According to datasheet: Maximum data transfer rate and gray scale control clock, are:33 MHz.I worked with 500 KHz shift registers before, in the similar projects with normal PCBs. In this case,do you have any recommendation for me to deisgn the proper PCB ?(Considering suitable thickness and length and places of the copper tracks in the PCB,specially for 33MHz.)

4-Does Texas Instrument have any other LED driver,whose GSCLK and SCLK frequency are greater than 33MHz and with 8 or 12 bits for PWM?

5-Don't you have any other special recommendations for me about this chip?

Your consideration is highly appreciated.

Marjan
