Quick question about Meta Keywords

[DejaVu]

I'm currently working on a site for perfume for a friend and need to know how I should layout the keywords for the site.

Should they be as keyWORDS seperated by commas?

Example -
joop, femme, eau, de, toilette, discount, fragrance, designer,


or as keyPHRASES -
joop femme, eau de toilette, discount fragrance, designer fragrance,


Which is the prefered? I was under the impression Google looks for phrases made up of your keywords, rather than full phrases that exist in them?

EDIT:
More to the point, if anyone can give any pointers on improving SEO (consoles?) I'd really appreciate it.
The site is @ http://www.scentsationalperfumes.com

It's not doing too badly, but he's trying to improve his exposure as he has some competition from a site @ http://www.scentsationalperfume.co.uk/ (who launched later).
