The GE futures (Globex Euro-Dollar) have a multiplier of 2500. Which mean each future is for about 250K. One interest rate basis point 0.01 = 25$, and the future is on the 3 month interbank rate.

The GE future options are the right (American style / physical delivery) for these futures.

If you are looking for books than read the excellent "Options as a Strategic Investment" by Lawrence G. McMillan. It's not specific for Euro-Dollar options but has a chapter on Future Options.
