I don't track it, it's my daily driver w/ about an hour a day spent in it split pretty evenly between highway and city traffic.
For now I'm sticking to 91/93, but I may go in on a FlexFuel kit in the next couple of years for some E85 goodness.
I've seen some conflicting info in this thread and elsewhere on what other equipment is needed for peace of mind with this super, e.g. extra oil coolers and injectors etc.
Is any of that really necessary for a daily driver? I'm in Las Vegas which right now is getting up to 110° F... should that make me concerned enough to burn some more cash on cooling?
Also, I have a station near me that sells 100 fuel. I know that performance increases cease pretty much at 93, but would the right tune get me anything out of it?

Is the extra cooling
required? No.
Will it be better for the car?
Yes.
How much cash you want to spend is up to you.
If you're not doing E-85 yet you can hold off on the injectors and fuel pump, yes you can run the C30 and stock (low boost) pulley and E-85 without upgrading them but again, it's better if you do.
A custom tune can get you gains with 100 octane but unless you can guarantee that you'll be running that in every single tank I wouldn't do it.
