Yes you can use 3 contents link and 1 referral links. it's allright according to the adsense policies.
You should keep the link to the Adsense Program policies in your bookmarks, since it has the definitive answer to your questions. If you ask here, some people just answer off the top of their head, even if they don't really know the answer: https://www.google.com/adsense/support/bin/answer.py?hl=en&answer=48182
yes one adsense unit is all you need ... if you put more is just to get more attention ... or you can put 3 ads ... one in the header one in the footer and somewhere else and see witch one gets more cliks and keep that one.
Really? Can i make it just 2 adsense: One a 300X250 and another small one on Post title (468X60)? Is that better than having 3 ads. The 3rd one is long vertical one.
