Hi Carlton,
With an SCT you need:
1 low-power eyepiece that gives the widest true field available for the size of the barrel - this means an eyepiece with no field stop inside the barrel. Focal length isn't important - could be anywhere from 25mm to 38mm. The type of eyepiece isn't important either as low-power ones are easy to design. A SWA for example would do nicely and these are under $100, an Erfle or a Plossl will do fine.
A couple of medium power eyepieces around 18 and 12mm, 12mm being a real sweet-spot for SCT's.
A couple of high-power eyepieces - for an f/10 SCT you will find 10, 9 and 7 useful.
