no, you can use 3 ads & 2 search bars, and I think at the same time you can have 2 referal products. Not to sure on much else offered by google.
google adsense allows three content ads and one search on each page and three referrals too.. so I think that would be fine
Read the Google AdSense TOS. You are eligible to place up to 3 AdSense for content blocks, 3 links blocks and 2 search bars per page.
