Custom CSS for Vbulletin and Header

I am looking to overhaul my website with some new graphics and a fresh new look. The site is www.macgenius.tv. 1. I am hoping to create a new header and an updated navigation bar. This navigation bar should have an updated new web 2.0 style. 2. I want to update the vbulletin forums to a new style. I have already chosen a theme that I feel will work well with [login to view URL] due to its rounded corners. You can see this theme on [login to view URL] (----Copy w/ Old Header) is the name of the style. I want this theme to be modified to be more in line with the "apple style". 3. The [login to view URL] should be compliment the new forums style, which should also be more web 2.0. 4. There is another portion of the site that is tutorials.macgenius.tv. Currently, we are looking to make this match the rest of the style of the site so we can publish this publicly. 5. I want a couple of mac logos although I do like the logo I have at www.macgenius.tv. I just want a few more so I can choose the best.
