any other files to backup before SL?

[o0revenger0o]

So i finally made up my mind and decided to move to SL.

 

Correct me if im wrong, is this all that should be backed up?

 

-KEXTs using OSx86tools

-My stuff using time machine on a separate partition?

-Partition image if SL fails using Norton Ghost?

 

BTW this is my setup

 

-intel pentium dual core e2140 1.6GHz

-MSI 4850 1GB DDR3. Will this work with SL with QE/CI and resolution change?

-SATA 320GB

-PS/2 mouse and keyboard (using additional KEXTs)

-Onboard Audio. Right now only rear port works. Im guess i'm okay with that.

 

Any help would be greatly appreciated.
