Joomla Templates

First of all hello to all as im new here

My question-
I made my site with joomla 1.5 template is black bear 1.5
I used jfusion frameless integration to integrate my phpbb3 forum into it.
Now all i want is to ask can anyone help me match the phpbb3 style with black bear 1.5 template?

Any help will be appreciated.And the phpBB3 style im using currently is the default style of phpBB3.

And sorry if this is something like spam.

Oh and.....how to remove the Blue colored header from the forums?
