Your first port of call should be the Resource (LINK) Page. This provides some good information about the various aspects of this App-a-thon and has links to several Microsoft videos also detailing these.
If the Resources page doesn't have the information that you need then be sure to check out the rest of the Knowledge Base. This is built up of lots of articles that others or ourselves have encountered with each problem having a solution.
