Here is the question:
Is there any chance that google are not listing me as I am paying for a keyword(s) I will be ranked high for and they know that I will remove the ads once the site is ranked correctly?
IE. I am only going to advertise with them until they list my site, as I know that it will come up in the top 5 when they do. Do they account for this or am I just being paranoid and I just haven't been added yet?
I have a domain where I used adwords ads from the time it opened. It has never had KW results above 30 on Google, but ranks #3 on Yahoo and #2 on MSN.
My other sites that that do not uses ads, or were well established before I started using adwords, all place in the top 10 for my KWs at Google
If your site is a couple of months old then google wont rank you well until you get lots of good quality incoming links, and even then you are at a disadvantage as your links will be new and I believe they give less weight to new links.
It takes time to rank in google compared to the others, I think you should assume you wont be ranking at all for 6 months, although more quality incoming links will always help.

This issue has been covered many times and answered by both GG and AWA.
There is no connection between your regular placement in the SERPS and your AdWords program.
Don't stress over it - it ain't happening.
