re-installing os x.

I am going to be reinstalling mac os x snow leopard because my computer is having a few issues which is caused by having the OS installed and being used for a while.
I need to reinstall my whole entire OS which will delete EVERYTHING!
what do I need to backup/save?
I have certificates and stuff from iOS provisioning profile.. can I just re-download them later from the ios provisioning profile? or do I need to back them up from the current os.

I probably would have done it but the frustration to get those set up was enough to lose the Linux sickness ;-)
thanks!
So it should work… Buy a Harddrive and run time machine also to have all your stuff.
Cheer.
