Reinstalling OSX after main system disk crash

Hi,
I want to restore and recover OSX & Logic 8 and the software i use with it (Apogee Maestro,UAD Quad & Waves plug-ins) to a new boot disk. I have both a back up of the main OS drive on a drive with Time Machine and a disk copy of the main drive (on another) as i had it before the boot disk crashed. My question is which is the best option to take when restoring the OS etc? As I have heard that there is a couple of bugs and issues when restoring via Time Machine. Is restoring via the disk copy a simple procedure? Or, should i reinstall everything completely from scratch and copy back the receipts and authorizations perhaps? Can you point me towards the best link/method to get my setup back on track?
Yours sincerely,
KFK
ps.. i'm using an apogee symphony pci card
