Best approach to integrating for a beginner

[Karrit]

I'm trying to integrate this smf forum:

http://celestial-star.com/sonny [nofollow]

I want it to look it's naturally a part of this layout:

Sonny Strait.biz [nofollow]

What's the best approach for a beginner? Would a portal be beneficial? And if so, could I use one without having to erase all the forum's information?
