Hi Tonya,
To change the color of the highlight tool, hightlight some text then right click on it and select Properties from the context menu. There you can select a different color. Once selected you can make that color the default by again right clicking on the highlight and choosing "Make Current Properties Default" in the context menu. Once you highlight the text it should stick with out the need for the highlight tool being activated. To not print the higlhlighted text, in the Print dialog ( FIle->Print) under the option "Comments and Forms' select "Document" only.
Hope this helps,
Dimitri
