Simple SEO Question

[Ben]

I'm a real SEO newbie, although I do try 

I'm designing a site for someone and I'm genuinely stumped as what his keywords (what people would search for to find his site) - do you use any suggestion tools? I've used a couple of online ones but I'm not really getting what I'm looking for.

The site is about Foo, but the suggestion tools just tell me obvious stuff like Foo+Bar, Extreme+Foo, Foo+Pictures - I'm looking for search terms related to the main keyword but don't include the main keyword.. if that makes sense.  Or do I just optimize for the +foo+ terms?

If that doesn't make sense.. then um, sorry.
