I like
these power jacks cause they don't take up a lot of space. I have tried the bigger plastic ones in the past but I have a couple cases where they snapped, though I chalk that up to the guitarist's environment. As for input jacks, I usually buy mono
switchcrafts but I've probably also bought
Neutriks cause they're cheaper. I dunno what kind of input jacks your gonna need but they've got stereo ones and smaller profile plastic ones as well. You can probably get away without led bezels and have them float or use some hot glue. 5mm LEDs are pretty standard, and they stock
metal bezels and
plastic ones. Personally I like clear LEDs but it's up to you, depending on what kind of switching you're doing you could use two color ones for settings or whatever.
As for the switches, I don't really know of anyones that are silent and latching, that is to say if you need a latching stomp switch. There are momentary switches which will be essentially silent but you'll have to be holding it down unless you know how to use a relay, at least I think that's the device. I like
these 3pdt switches for pedals, but you could also use a dpdt switch and wire up a millennium bypass circuit for the LED.
