Your HD problem could be related to the drive being a SATA 3 drive and your Mac is SATA 2. Look at the HD docs for a jumper to set to SATA 1/2 compatibility. As far as getting to Mountain Lion, once you get Snow Leopard running (via DVD) you'll be OK in getting it upgraded to Mountain Lion via the App Store (make sure you have a good & fast internet connection). Or, if you use the migration tool with your older HD in the other system connected to a common Ethernet network or via an external HD case via FireWire to this system you'll be able to transfer all of the files to your new HD, then you can upgrade to Lion (DVD or flash drive) or Mountain Lion via App Store.
