Cisco Switching/Routing :: Changing 4510-SUP-6E Redundant Mode To Share-Backplane Mode

I received the following info from Cisco's TAC and wanted to inquire further before I start reconfiguring the switch:
 
In a redundant Sup-6E setup, the following configuration is supported :
 
- 1 TenGig uplink on Active Sup and 1 TenGig uplink on Standby Sup
- 1 TenGig uplink on Active Sup and 2 Gig uplinks on Standby Sup
- 2 Gig uplinks on Active Sup and 1 TenGig uplink on Standby Sup
- 2 Gig uplink on Active Sup and 2 Gig uplinks on Standby Sup
 
If you invoke shared backplane mode, the following configuration can also be supported:
 
- 2 TenGig uplinks(blocking) on Active Sup and 2 TenGig uplinks on Standby Sup
- 2 TenGig uplink(blocking) on Active Sup and 4 Gig uplinks on Standby Sup
- 4 Gig uplinks on Active Sup and 2 TenGig uplinks(blocking) on Standby Sup
- 4 Gig uplink on Active Sup and 4 Gig uplinks on Standby Sup
 
Here's the command and information about the "shared-backplane" mode :- [URL]
 
Currently, we have 2  SUP 6-Es(Module 5 - Active and Module 6 - Stand-by) setup in a redundent mode. I am planning on changing the redundent mode to the shared backplane mode so I can use 2 TenGig converters to uplink 2 access-switches. We purchased 2 TenGig converters and here is how I am planning on using them:

1- One will be used  to uplink to two 3750 switches(stacked)
2- One will be used to uplink to a 2960 using a Gig SFP
 
My questions are:

1- Do I have to install the 2 TenGig converters(4-Gig Uplinks) in the same Module? Or can I use one one in module 5 and the second one in module 6?
2- Will changing the redundant mode to the shared backplane mode require rebooting the switch or disrupt the funtionality of the other linecards?
