I am still not really clear in my head in terms of how it all fits together - especially when I start reading some of the CCD info re "self-guiding" etc - do some of them not need OAG? Sorry for all the questions!!

The sbig Stt 8300 has the option to go for a self guided filter wheel, meaning it has a small ccd before the filters that can guide. With this option there is no need for another oag or guide camera. Keep in mind though if your first go at astrophotographers is shooting at long focal length with a mono ccd and self guided camera there is a lot of learning to do. This is definitely jumping into the deep end of astronomy. Not impossible but there will do many frustrating nights ahead. You should also think about the type of targets you want to image and what field of view your scope and ccd will give. If you want to image say the Orion Nebula then the set up you are talking about will require you to stitch quite a few images together in a mosaic .
