vB4 CMS category set-up

I'm hoping to try the suite out when we see 4.0.3 and move my terribly outdated 'homepage' into the CMS. My SEO question would be on setting up my categories. I know I need to create a few pages in CMS that mimic my old site with custom rewrites so I don't lose my sitelinks.

Should I set the categories up differently named than my forum categories or would it be alright to set them up the same as my forum?

I would suggest naming your categories up for the actual content that they hold.
