Are these links still 'seo friendly'?

[TcM]

Well I am trying to optimize my website and I was wondering if

www.mywebsite.com/review.php?sid=17_business_business name_description_short description here

is better then:

www.mywebsite.com/review.php?sid=17&reccat=1

A) What do you think? Is the first one more SEO friendly then the second one? or it won't make any difference as it still has the ? and =

B) the URL will have spaces in it, will that hurt SEO?

C) You think that I should implement it? or not?

D) If yes then should I use _ or -

Thanks for your responses!!

Well I read elsewhere that no, it is not SEO friendly but now I'm trying to do it with htaccess and PHP.. hope it works out.
