Need help here frnds!!!!!!!!!!!!

I have a little problem with my vette.This morning when i turned the ignition on.i had a warning says low volt.I guess i`t`s time to change the battery.And also last 4,5 days headlights,interior lights,and dashlight were acting weird too.They `re blinking every minute or so,Of course fist thing i `am gonna check the connections of the battery.The thing that i wanna know since C5s r very computerized.if i need to change the battery do i have to do something special before or after i change it.I`ve done this alot of times on my other cars before.But u know C5,How delicate it is.Any 02 would be helpful thnks again.
