Help with nRF24L01+ datasheet

I'm trying to figure out two things.

 

1) There is a section on timing but I'm a bit confused what SPI Clock rate to use (SPI2x, SPR1, SPr0 respectively).  I don't see a way to set the nRF24 via pins (as there clearly are none for clock rate) so I'm left to assume the clock rate is fixed.

 

2) When setting map tables, what is the packet format of the SPI data?

I see the Register map table and  that you set them with SPI. But how is unclear. I would have expected to see something like.  [command, addressHI, adressLO, byte1, byte2, byte3, etc....]. The ShockBurst appears to have packet data but does not seem to be what I'm looking for.
 

I'm sure its all there just need help.

That is required, since the packet is triggered to be sent in TX. In RX is should be high all the time while receiving.

That works, got most everything set up but the receiver. Receiver is now on ARM and my receive codes is something like

spi_send(2,0x61,0x00,0x00,0x00,0x00,0x00,0x00,0x00); //get state
spi_send(1,0xe2,0x00,0x00,0x00,0x00,0x00,0x00,0x00); //flush

I always get 0x0e empty fifo but I also get the data i'm looking for. I want to basically get the data and dump the buffer so I always have fresh data. I'm not able to make that work.

I'm thinking maybe I need to use 27 or 37 hex and set the flags but i'm not sure.
