Beginner Problems with Noise & ISO - Should I Upgrade my camera, or my Lens ?

Totally incrrect advice.

Noise is mostly always in the darker areas (shadows) by under exposing you introduce more dark areas to the image and therefore more noise and when you amplify it by correcting the exposure it shows even more!

Get the exposure right or even over expose slightly to reduce the noise in your images

Google "ETTR" (expose to the right)

Not quite the reason why under-exposing increases noise. It's because raising ISO amplifies the signal before the analogue-to-digital converter gets hold of it, and it's far more efficient than after the A/D converter, ie in post processing.
