It depends on whether your DSDT/SSDTs contain the definitions APSS and ACST. If they do, the definitions must be removed or the table dropped.
Otherwise, which is the common case, you can use the new SSDT without dropping your OEM SSDTs. Make sure to disable the state generation as they are in the new SSDT.

This is its official site where you will always get the newest version: https://github.com/P...ls/ssdtPRGen.sh
You don't need to install it, you just start it without any arguments and it shows you the process, hopefully including error messages.

I don't know your exact configuration; it is possible that currently your CPU does not use its turbo modes. Besides, you should switch to the Ivy Bridge power management anyway.

Hi again, is your current setup working well without any shutdown problems? Some time has passed now and I'm sure the issue would have appeared several times by now, if at all.

Both are considered "normal" warnings and can safely be ignored.

However, as you got an Ivy Bridge CPU, you should switch to another power management plugin: search for a script named ssdtPRGen.sh. Running the system with the produced SSDT will show a different warning affecting the "ring table" that can also be ignored.

Hard to say.. you obviously didn't have any problems when installing OS X the last time.
You can try plugging the drive into another SATA port, verify the BIOS settings and do a CMOS reset.
