Sadly there are no guides outside of experience and rules of thumb. Looking at tech charts is about as good as a resource as you will get!

Certainly a 6.5 is not the wrong motor for a 4wd buggy, you will find it a little easier to drive than a 5.5, and often easier to drive is faster round the track anyway!

Lower turn motors generally rev higher, create more power, and create a little less torque. Gearing is based on the "feel" of the car on the track (gear down for more punch, gear up for more top end, within reasonable limits), and also to stop the electrics from overheating. Although brushless motors tend to have ample punch with any gearing.

Curious as to why you are choosing a Spektrum DX7 and the Ace servo tough - wouldn't be my first choice for electric buggy racing. DX7 is a flight transmitter, Ace is a fine servo but more intended for nitro.
