Different Drop down menu for homepage in Thesis Theme

I’m using the Thesis theme. Does anyone know if there is a plugin for wordpress that would enable me to have two different drop down menus depending on which page a customer visits. Or whether such functionality exists within the Thesis theme.

I want my service page which will be my home page to only display dropdown menu items related to the service – contact, about, portfolio, prices etc. I also want a blog on the same website but for it to be hidden from the home page so that the customer isn’t distracted. On the blog page it will list categories or pages related to my blog.

Thank you for your help
