foodie pro theme logo bigger?

I have 3 questions 1. can I make the site identity logo bigger in size? 2. On individual pages can I turn off the "adnmin" and "date" that appears in the header on each page? 3. And also... I changed the fonts though the pro settings but the page titles still show in the header image in the original font. they should be PT sans sorry for all the question love the theme site : http://new.bluewaterconventioncenter.porthuroncam.com/
