Thanks for all the comments/feedback.
AdsensePlugin – I’ll take a look at the colour of the font. This is something the designer decided upon, I did change it on either the blog or the website I’m sure as I did recognise this issue, so I’ll take another look.
The reason I used separate domains and hosting for the blog and main website was to help in promoting the main site. I can obviously post relevant SEO’d content and anchor text backlinks to the main site. However initially I wanted the whole site/blog as one WordPress site. I recognise that the main site does not have search engine friendly URLs, which is a downside.
Thanks again everyone.
