Hi Pete. Breath into a paper bag and beg forbearance from SWMBO and your 9yo. 
:-D

The clone is there as a safety net. If something goes dramatically wrong (and 
there is no reason to believe it will) you can copy the clone back onto your 
MacBook -- no harm no fowl.

Firstly I would take one step at a time and would *not* use this as an 
opportunity to upgrade the OS. Get your system tuned perfectly and Time Machine 
working again and then perform the upgrade if you choose. You will need to 
check the model of you MacBook in any case to see wheter it can be upgraded to 
10.6 or not.

If I understand correctly the machine currently is running 10.5.8 and you have 
a OS X disk with 10.5.4. That should not be a problem. 

1) Run the install over the top of the current installation using the 10.5.4 
disk.
2) Repair permission.
3) Get Time Machine functioning and allow it to finish backing up.
4) Download and and run any software updates from Apple Menu > Software 
Update...

This should get you in a good position to do the OS upgrade if you choose.

If you need help with the upgrade, feel free to start a new thread and we will 
help where we can.

Regards,
Carlo
