Do the outbound links influence your pagerank? Do you suggest that we put always rel="nofollow" in every ad we have on our websites to keep our PR intact?

IMO... Yes and maybe.
PR will not go down if you link to many relevant, legitimate websites.
PR will go down if you link to bad neighborhoods, the linking looks funny (like you're part of a link farm), or if it looks like you're selling links.
I would nofollow any link that isn't the same topic as your website. But you should have some leeway, since many legitimate sites will have a small number of links to pretty unrelated websites. e.g. e-commerce links, widget links, etc.
