Ok here are all the settings i changed prior to reinstalling Leopard:
Under the system menu of Secrets i did the following:
Checked the box for "Beep feedback"
Changed the "Crash Dialog" from Basic to None
Unchecked the box for "Enable Quarantine" box
Changed the "LCD Font Smoothing" from Standard to Strong
Unchecked the boxes for "Leopard Appearance: Use Core UI" and "Use Leopard window values"
Secrets automatically had the boxes "Enable Quartz 2D Extreme" and "Quartz GL Enabled" checked
Under the Finder section i changed the following:
Desktop Icon size to 48 px
unchecked the animate get info panes box
unchecked ALL of the finder animation boxes
Checked the boxes for "Prohibit Animations" and "Prohibit access to iDisk" (since i dont use iDisk)
Disabled "Calculator" and "Dictionary" spotlight options
that is pretty much it other than enabling "Debug" menus for all programs that had the option
Oh and also i changed BeamSync from Automatic to Disabled (I suppose i could also change it to "Force")
