Talk of "Minimal tools" and multiple vises and fixture plates probably should not be in the same sentence! And particularly not if you have no specific projects in mind.
I assume that you have a way to cut stock to size.
As a start I would purchase a clamp set, a single vise (I mostly use an overpriced 4-inch Kurt on my 770), a set of parallels, a half-dozen TTS holders (I prefer ER16 ones for both endmills and drills) together with collets, and a selection of endmills (I have gotten good results in aluminum with the Shars ZrN coated ones but YG1, Maritool and others make excellent products). You will certainly break some endmills so I would get a half-dozen of each of perhaps 1/8, 1/4 and 3/8 ones. Depending on your need for small holes you could purchase a set of drills from a quality maker such as Precision Drills. Alternatively, purchase only tap and clearance drills in sizes appropriate for your work.
I assume that you have an edge finder and a way of setting the Z-height from your Taig work. If not, a Haimer 3D Taster might be a good purchase.
A pendant such as the Tormach shuttle will be very helpful. Adding a Power Drawbar will be super useful but certainly not essential to start. Don't forget a selection of stock to work with.
As you gain experience and tackle new projects you may want to explore using soft jaws (Monster Jaws are almost the same price as raw stock). And a way to surface stock such as the Tormach Superfly or a cheap far-East face mill. And of course spare inserts for your Superfly or whatever you choose.
Although their prices are not the cheapest, Tormach has all of the above items on their website and may be a good source for a beginning user.
Enjoy your new toy!
