Hi Canbez - I think George is resting at the pond, so let me try to assist you.
1. Changing the top of the Occasions theme is going to require the skills of someone who knows how to use CSS and HTML, this theme wasn't built to house a logo there so the code will need to be changed in order to achieve it. It's not too tricky though and the developer would more the likely have to make a few changes to your styles.css and header.php files - another developer with knowledge of CSS and HTML should be able to assist you quite easily and it shouldn't take them more than an hour. We, unfortunately, do not offer customization of our themes as a service as the man hours it incurs would mean that we don't have any time left to build beautiful themes.
2. With regards to the featured images not working, this is a TimThumb problem, which isn't related to our themes per say. That being said, we've written a blog post about this very problem and it should assist you: http://www.efrogthemes.com/tips-and-tricks/timthumb-not-displaying-images-lets-fix-that/
I hope this can get you going!
