You should be just fine with RE-850-1536-R. The M10i has 6.4 Gbps full
duplex forwarding capacity, so six GigE ports should be okay.

PE-4GE-TYPE1-SFP-IQ2 is overbooked. It has *one* full duplex GigE link
to the backplane. For six wirespeed ports you will need PE-1GE-SFP,
distributed over the two CFEBs.

Yes. Note that list price for 6 x PE-1GE-SFP is higher than *one* 20
port DPCE-R-Q-20GE-SFP GigE card for the MX series. I would strongly
urge you to consider the MX series here.
