How much current can I put into my RPi?

What is the maximum current (supply of) that can go into the RPi before you do serious damage? Would a 5v 2.1A adapter benefit me in anyway if I am using:

15m Ethernet cable

USB flash drive

mouse + Keyboard

HDMI screen

and have overclock the device to ARM=932MHz/GPU=350MHz/RAM=500MHz

... Instead of a 5v 1A charger?

Is this what you are also talking about?
Yes. You can power a RasPi that way if both of these are true:

1. Your USB hub is able to source current through its upstream port. This is not standard USB hub operation, but some hubs do it anyway.

2. Your RasPi's downstream USB port is not protected by a 140 mA polyfuse F1 or F2 because:
a) It's a rev 2.0 RasPi which does not have F1+F2, or
b) It's a newer rev 1.0 RasPi which replaces polyfuses F1+F2 with 0 Ohm resistors, or
c) You have modified an older 1.0 RasPi to short out F1+F2, violating the warranty.
