Hi KG,
1.These service will be impacted becaue router will be reloaded
2.Normally, you may upgrade the firmware after XR upgrade
3.2Gig is enough for 4.0.0 release
4.You may install all packages at once so minimize the downtime.
I would recommend to check the procedure
http://www.cisco.com/web/Cisco_IOS_XR_Software/pdf/CRS-1_Upgrade_Procedure_3_6_x_3_9_x_to_4_0_0.pdf
It is detailed and describing all necessary steps.
