Thank you very much! is there a reason why the tone should be first? Sorry I'm still learning about wiring.
Yup. I use this wiring all the time and it works great! I typically use a push-pull volume or tone control for the switch rather than a mini switch and that works very well and means you don't have to drill anything. Also my "standard" electronics mod on my SX Jazz bass clones is not to use a push-pull or mini-switch but instead to use a rotary switch. So I change vol-vol-tone to master vol, rotary switch, tone. The rotary switch has 5 positions: Neck pickup only, neck + bridge series, neck + bridge parallel, bridge pickup only, and mute. With single coil pickups, the soloed pickup positions will have a bit more hum. Diagram is here: http://www.mrk-inc.com/users/bspam/SXDummy01.bmp Just short the wires marked "dummy" because a dummy coil there will change the tone of soloed pickups so that idea didn't work so well.
My plan is to keep the metal cover plate as is, and just use a bushing nut threaded to fit the 1/4" mini switch diameter to take up the extra room for the 3/8ths mounting hole. I hope this makes sense. That way there will be no need for drilling.
I almost always rock both pickups at full volume to kill the hum, so I saw no need (at least for me) to have 2 volumes. this is why I like that master volume idea. The series/parallel switch would be just for additional tonal possibilities.
