How can I take away the security light ?

I will be having a head gasket replaced on my vehicle. The vehicle will have been sitting a while before the mechanic I've selected can get to it. So, I have two questions-what can I do to "refresh" the gas (the tank presently holds @39 gallons, since I had tanked up before I drove 15 miles and had the gasket blow)? Also, since water got into the block, what sort of aftercare ought I to do to keep the vehicle in good repair, and attempt to prevent future failures?

Thanks ahead of time!
