I need to know how to draw, or add my own typing, over a pdf. I have a worksheet in pdf format, and instead of printing out the papers, I just want to be able to insert my own typing and underline things (as if I used a pen/pencil) directly on the document. Does anyone know how, or any programs that allow this?

Sounds like you are under the gun.

Many members already use the Foxit PDF Reader. Its free and very light. Saves loads of time and space over Adobe PDF reader.
Now you can try the Foxit PDF Editor for Free for six months. We will be expecting a report at some time.

I think you best bet would be to use PDF2Word v3.0 which will convert your PDF file to a Word document so you can add or change what ever you want too. Just looking on there site and they do a VeryPDF PDF Editor but I have no experience of this application. Or PDF Editor Toolkit if you want to make your own PDF files.

The Foxit Reader is just a PDF reader the same as Adobe is you can't edit the files.

you seem to be able to edit pdf's within the next release of openoffice/star office thanks to a free add on .... converts pdf to odf then exports as pdf again

You can try this one, I have found it quite helpful in this regard, and it is free:
