blue host and my blog

I was sent here from WordPress.com. Hope you can help.
I have a wordpress.com blog. Wanted to have a store and was told I would have to go to someone like bluehost. So I did. I now have two wordpress templates on bluehost. One for my blog and one to be used as a website.

Question: How to I add the wordpress.com blog to my wordpress template I am using for my website. I also want to add a store etc. to the website besides the blog.

Bluehost said I should contact wordpress for assistance. Hope someone out there can direct me to what I should do. If you want my address I will provide. Did not know if I should provide here.

Thank you for assistance …I can write and do easy websites however, this is way beyond me and will take me day and weeks to understand if I do not receive some guidance. Appreciate any guidance you might provide.
