Adruino GPS, temperature, light intensity

I have a Adruino 328 Mega board with a GPS Shield. I have code that I got from open source that works well. I need to modify the code to do several things:

1. I need to change the way it names the file it writes to SD Disk. Basically, instead of GPSLog...I need GPS01Log. I will create 16 different versions of the sketch that label GPS01Log..GPS02Log...GPS03Log. I have 16 of these units that i need the files named differently. It would be even better if the file name could be named with the date and time the log starts. I will need directions with the completed work that tell me how to perform the edit to create multiple sketches to name each GPS.

2. I need to be able to set the log interval. I want to be able to set it log every minute, or every 2 minutes, or every hour....basically whatever interval I choose. I need the interval to be exact and log the time on exactly a minute or the interval I have set.

3. In between log times I want to make the GPS sleep. It is drawing about 70mA of power that I need to conserve in the battery.

I need these three custom changes made to the code. The current code is posted at the url below. The file is called GPS CSV logging sketch and the library is called AF SDLog Library. I am sure this is easy for a experienced programmer. <[url removed, login to view]>
