Google maps and copyright Q.'s

Hi there all!
This is my first posting on the flying startups site, and felt it was about time after reading the book, listening to the podcasts and buying the T-shirt (well ok, maybe if they made T-shirts I would have!).

I am month 5 into my business idea and have undertaken my own market reaserch as well as completed a full analysis of my competition. My business plan is nearly complete and my marketing strategy is growing by the day. The business is going to be a web based business where members sign up for a small fee for some amazing perks (they can also trial for free) however at this stage can't say any more than that otherwise I may have to kill you!! I am yet to decide who to design and develop my website (the quotes are coming back now). I never realised that it would be so taxing deciding who to build the site! Nevertheless I am enjoying every minute and the freedom that comes with preparing and starting my own business.

However I have a couple of questions for people:

Firstly, if I want to include a map on my website that users can add information onto (i.e. listings) am i permitted to use Google maps?

Secondly, one of the web designers/developers has asked to keep the copyrights of the brand/logo for a limited amount of time then sell it back to me on a set fee once the business is successful. None of the other developers/designers have asked that. I already have a logo, and do understand that if software/database has been created by them that would be the only the part of the website that they own the copyright to.....not the brand or logo. Am I correct or have I lost my mind?

Thanks so much fellow startups!
