Jeremy of PPC discussions has a very good write up on Frequently asked questions about Google adwords quality score.
Check out his postings here

Some of the questions answered:

Question 1 - How can I improve my quality score?
Question 2 - How many quality scores are there?
Question 3 - Will changing to a different keyword match type, for example from broad match to exact match, give me a better quality score?
Question 4 - I have been told (and read lots of places) that when I first start a new AdWords campaign I should bid really high so my ad is higher on the page. That will give me a higher click through rate and that means I will have a better quality score. Is that good advice?
Question 5 - Having Flash on your landing page is bad for your quality score right?
Question 6 - I get a lot of clicks from the Google Search Network. Does that help improve my quality score?
Question 7 - Does using dynamic keyword insertion help my quality score?
Question 8 - Does turning off the content network help improve my quality score? My CTR is always a lot lower on the content network so I assume turning it off will help my quality score improve.
Question 9 - How can I find out what my quality score is?
Question 10 - I am the only person bidding on a certain keyword but my minimum bid is higher than I think it should be. If I'm the only one bidding how come my minimum bid isn't $0.01? My quality score is "OK".
Question 11 - I just a made a lot of changes to my AdWords campaigns and to my landing pages to try and improve my quality score. How soon should I expect to see quality score changes in my account?
Question 12 - I just added a bunch of new keywords to my account and almost 1/2 of them received a poor quality score and minimum bid of $5.00 right away before I ever received a single impression. How the hell can Google say I have a poor quality score before my ad even gets a chance to run?
Question 13 - It seems like no matter what I do or try my quality score is always poor. Are there certain types of sites that just don't work well with AdWords?
Question 14 - Is there a site or something I can sign up to find out in advance about quality score updates before they happen?
