Sway bar links/suspension noise

[JDM]

I have a noise coming from the rear and the front both sides of the car which seems to get worse as the car heats up after driving a while - it's most noticeable at low speeds and when I hit a road break or a speed bump. I have made my research to PCA.ORG and according to similar cases mentioned in the site

" The number one cause of suspension noise are bad sway bar links "

Now my questions are as follows :

a ) if has anyone until now have a similar noise problem and solve it after the replacement of the sway bar links or another suspension part .
b) Should i take the opportunity to change something else also now on the suspension system except of the sway bar links.

thanks.
