Well I've finally done it, Intergrated my WP blog theme with bbPress. It's not as hard as you think once you look around. Anyway check out my intergration here:

(There are still 1 or two minor CSS errors but the intergration of Wordpress functions has been done successfully.
It's taken me a few days to figure it all out, but I've finally done it. Although it does sound like im bragging alot. I also want to share a website that could also help you do theme intergration:
http://bbpressraw.com/bbpress_blank_themes/
This site provides blank themes that are literally the bare minimum of CSS, but even better they provide blank themes in type so for example my blog layout is a 2 Column design. I would also find this layout on bbpressraw.com and then begin editing it.
Being able to get a pre-coded layout with the bare minimum needed within it, certainly helped me alot. And I was able to understand and modify to intergrate my blog theme into it.
I hope this website can help you to in intergrating your bbPress installation
