Gear Inches = (number of crank chainring teeth) x 27 / (number of hub cog teeth). It is just a number that is used to talk gearing. A bigger GI is a bigger gear and a lower GI is a lower gear. So for example if you have a 46T chainring and a 17T cog, then your GI = 46 X 27 / 17 = 73.
Toe overlap is how much your toes overlap the front tire when you turn the bars and your cranks are horizontal. If you have a true track frame with tight geometry, then you probably have a lot of overlap. This just means you have to watch your pedal position when you turn the bars.
