Usually people tend to use a 250 K pot for a single coil and either 250k or 500 k for the disc piezo. On the volume pots the 3 lugs are lug 1 hot in, lug 2 hot out, lug 3 is connected to ground (usually by bending the lug up and back so it touches the side of the pot and soldered into place, the back of the pot is in turn wired to ground.
The 3 way looks nothing like the picture but look at the bottom of it to see how the connections are like the diagram. Note you wire to the opposite side connection on the 3 way to the position of the pickup as per the diagrams this way the toggle points to the pickup position you have selected.
The tone is wired as per your wishes via the jack socket terminals. Due to the physics of the piezo the usual pot/cap combo used for an electric guitar tone has little effect on a piezo (they make a high pass circuit letting higher frequencies through). With this circuit you will get a working tone with the single coil but single coil + piezo or piezo it will give little tonal control. You will get 3 different and useable sounds though.
Tone control capacitor for a single coil is normally 22 or 47 nF (0.022uF or 0.047uF) personal choice and the 47 rolls off more of the upper frequency than the 22. Pot value either 250k or 500k,
Note pots can be log (=alpha) or linear (= beta). Some debate as to what is better for volume or tone. Hearing works on a log scale so I tend to go for log pots to mirror my hearing. Linear pots will work too but more effect over a smaller part of the pot range. Some players like this as it means a quicker response playing live. For tone I prefer linear so a bigger range to work with, other prefer less. All down to personal choice but either type will work.
Strings ground means especially for single coils you need to find a way of running a wire to the strings and connecting to the ground side of your circuit. It helps reduce the electric mains hum the strings detect.
If you have never soldered before wear long sleeves and eye protection. It is rare but the solder can spit. To help the solder stick to the back of the pot rub the back with a file or sand paper - it has an oily coating that can stop a proper solder joint to form. Check on YouTube for how to solder. A cheap multimeter costs only a few dollars and ones with a continuity detector function lets you test each solder joint as you go. If you need something to help hold the bits as you solder check out “helping hands” on Amazon or eBay - moveable clips and a built in magnifying glass.
There are 3 photos - complete circuit, the positive wires, the negative wires so you can see what goes where. On the complete circuit the hatched triangle indicates a point to join all these wires to the common ground and ultimately the sleeve of the jack socket.
Thanks David.. I have been in the house for a month and weeks to go... Trying to wire up single coil in the neck position, piezo in the bridge both have two wires, separate volume control for each one then a master tone control to the output jack.. My first build and don't know how to play, but needed something to occupy my time during the winter since I am disabled and the cold hurts... Summer I shoot airguns off the bench. Tremors make it a challenge..
There has been a relevant posting on the general forum by Michael Gadjeski on "Diy effects for beginners"
I have added the link here http://www.cigarboxnation.com/forum/topics/diy-effects-for-beginners
it links to other sites with schematics foe guitar effects.

Mind you OK nothing to do with CBGs but the Danelectro diagram is wrong! If it's for a U2 anyway as they're odd bcz they're wired in series not parallel!
Not a standard Gibson style switch!
This is excellent David!
Kent Armstrong have a wiring page which is far less extensive BUT might be just the thing for people who are making a simple CBG and are less experienced and want a more pictorial diagram. http://www.kentarmstrong.com/KA_Wiring_Instructions.pdf
