Thank you all for your insights, I would love to buy another bit of software to make this task easier, but it is a hobby and as such one that has a limiter in the form of SWMBO. I already have Fast Stone something or other for batch resizing, so I will try their product.
It seems that the methodology is very similar between many of you and as such will be a good place to start from. Following this situation my Christmas wish list contains a couple of larger CF cards to allow me to shot JPEG and raw again. This will likely be my first and last raw only shoot as the lack of JPEG for preview has made this very slow / require faster viewing software. I will also try to limit the number of shots I take, I will find out how that goes at the Goodwood Revival next Sunday. We go to collect money for charity for a couple of hours but that gets us the rest of the day there to enjoy!
The "G" button sounds really useful, especially with the side by side comparison.
Once again thank you to all for your input, it is extremely helpful.
