Hi Mat, that looks like a very capable collection of machines. I haven't seen very many Myfords in these parts and I believe This Old Tony (Youtube) has a Colchester Student, but I'm not sure about the size vintage, model, etc. He's able to make some very heavy cuts though, so you're probably in possession of a pretty serious machine.
Here are some photos of my shop. I've got a 7x12 Mini Lathe, CNC Mini Mill and vise mounted on a homemade workbench with a steel-reinforced concrete slab on top. The slab sits on top of a few layers of carpet underlay and I've found this helps keep vibration from propagating into the rest of the house (My workshop used to be in the top floor of a townhouse). The high mass of the slab also makes working with the vise really nice.
The mill was converted to CNC using a kit from CNC Fusion and the electronics consist of some Chinese stepper motor drivers and a Xulifeng AKZ250 USB motion controller. I've certainly taken a hit with regards to simplicity and productivity by converting the mill to CNC but it's also allowed me to do things that I couldn't have done with a manual machine, so no regrets.
The wooden crate on the left end of my workbench is a 12x18 granite surface plate that I got from Busy Bee recently. I used it for the first time when making a pair of tapered saddle gibs for the lathe and one day I want to use it try to improve the fit of the cross slide and compound on my mini lathe.
The last photo is of my metal stock collection. It's mostly scrapbinium and unknownium, but there's enough to keep me busy for quite a while ;-)
