I'm getting ready to launch a new business (not hosting). Got my domain but I also have a bucket load of domains that relate to my site. So the question is what's the best use of these? Should I simply have all of them forward to my site?

Your thoughts are appreciated!

If they are variants of the name, yes.

Hi,
I would forward them all.

They're not all variants. Some are unique domains that someone might naturally look to when searching for our products. I had thought that for some it might be more effective (google-wise) to simply host a single page with a link or links to my main site.

You might make a gateway page with a ppc.
