Print mashup: How can I have info of features and projects

Hi,

I am doing a print cards mashup for tasks, bugs and US.
If I print a task I want to see the id and name of the user story that it is linked to and the ID and name of the project that the task belongs;
If I print a bug, I want to see the US id and name that it is linked to and the ID and name of the feature and project that the bug belongs to
If I print a US i want to see the ID and name of the feature and project that the bug belongs to.

Can you please tell me how can I have that info in javascript and calling the API? Thanks.
