Setting up custom posts and taxonomies

Hey guys,

I am new to custom posts and taxonomies so need help setting them up. So I am trying to create a post system for reports.

Its something like this.

Reports [ Daily, Weekly, Monthly, Quarterly, Annual. Special]

Products include : Gold, Silver, Oil, Cotton, Sugar, Rice, Maize etc.

An example of a post would be:

Daily report of Gold prices , Daily report of Oil prices etc.

tags or custom fields would be uptrend, downtrend etc. etc.

I just need some advice creating an automatic system so I click on add new report, select gold, select uptrend etc. and it would show up on the gold reports page. I have tried to make it work but not sure how to implement it. Any advice or article to see a detailed example would be great.
