I think you'll struggle with a 540 motor on 3s. They are designed for 2s. 2s on 4.5 - 5.5 is a much better option. The car is awesome and plenty of info on the Serpent site and the Facebook page (just search Serpent 748e on Facebook). It doesn't come with a pinion (as all pro level cars) but the spur is 48dp. Use the calculator on the serpent site to choose the right pinion which is depended on cells count, tyre diameter and spur.
