How can I eliminate noise coming from my amp/pedals when they are on?

I have a fender tube amp, a Boss MT-2 Metal Zone, and Dunlop Cry Baby wah and between those three I get a lot of hum/buzz

I used to get humm from my pedal board, I grounded the jumper cable of the input jack of my last pedal before the amp and it all went away. I also noticed if I simply held the strings of the guitar while I wasn't playing it'd take away the humm.

I have an MT-2 also... How high do you have its gain? That thing gets noisy... I keep mine at around 10:00, and its very quiet. I dont suffer from loss of gain either (i play metalcore, i need lots of that...) Just make sure you have it at a good EQ setting. It could always be your amp.
For effect pedals you can add the Millenium Bypass mod. -Buster

. Inspect the shielding, ground, and signal connections on all your cables/boxes/instruments. Repair/replace as needed. That should get rid of most of the hum/buzz. . Shorting the pedal output (or amp input) should kill all hum/buzz. If you short the amp input and still have hum, then the problem is in the amp.

what does shorting mean? How do I inspect signal connections/shielding... I have a very small knowledge of wiring
. Shorting just means to connect the signal line to ground. This should give the amp 0.00V input (total silence). . For a Quick&Dirty test of the cables, flex them in different places. If you find a spot that causes the hum to start or stop, you've found a spot that needs attention. Since you don't know much about wiring, you may be better off just replacing the cables. . Make sure all shields inside the pedals and instruments are in place and connected to ground. An ohmmeter will come in handy for this. . Make sure all signal and ground connections are "tight." Look for corrosion, broken wires, &c. Grab wires near the solder point and wiggle - any crackling noise from the amp means a bad connection. (If you touch the wrong wire/spot you will get a LOT of 60-cycle hum - this is normal.)
insert a quarter inch rod of metal into the INPUT (make sure its long enough to get it out) - it will tell the amp that there is absolutely 'zero' happening outside. If you still have noise coming out when you have that rod inserted, then the amp has noise coming in from elsewhere - bad connections, components, or power supply.
