I think you need to either clean or replace your TPS as its basically tell you its open but can't open or close it itself.

The noise is probably the lash adjusters. A VERY popular upgrade is the 3mm holed lash adjusters, they reduce the noise

Lash adjuster keeps the gap between the cam and the valve minimal at all times by running oil under pressure into the vessel. They can be done at the same time as the belt, but not necessary They won't be doing any damage, just being noisy.
