Knee problems are generally a symptom of a problem somewhere else, the hips for instance or your running style.
Short term I would sign up for some circuit training to improve your core strength; this could be a cure in itself.
But longer term, consulting a physio is a good idea, this 'popping' sound is interesting, a physio would need to examine it for any sensible diagnosis.
Getting a running friend to tell you how your running style looks; leaning forward, tense, etc. or get someone to film you while running would be interesting then compare with other runners.
There is a wealth of self help material out there (books and websites) that advise you on running style. 'Chi running' springs to mind as an example (can't endorse it though as I have not tried it!).
