hehe, marcus: all good ideas. as sna was saying RE-Search is a good place for people to submit tutorials on the website. In time we hope to grow this area of the site to produce the net's only complete reversing search engine.
As for recommended tools: I would recommend any of the tools that RET members have released. If you are looking for a specific application that they don't offer, you should check out http://protools.cjb.net
for their recommendations.
