RAID 1 ----- Can I mix HD's with slighly different specs?

IIRC, RAID 1 is simply a hard drive clone. As long as capacity is the same, performance specs and form factor should not matter in that case.

Be sure to use a journaling file system.

This will be just fine. Disk size can be different but the array will have the capacity of the smallest drive.
