where are this two 10G ports ? are they the same as GigabitEthernet1/1/1 and GigabitEthernet1/1/2

I think they are there from the beginning in case you provision a module. You have a 1 Gbit module but there is also a 10 Gbit module called C3KX-NM-10G. See the hardware guide here:

The 3750X series can accomodate a 10GB module which allows for 4x 1GB or 2x 10GB so I believe those ports are provisioned for if you want to use the 10GB module.
Just ignore them as configuring them will do nothing unless you have the 10GB module.
