This will change the page...
this.pageNum=this.getField(YOURBOXNAME).value-1;
I have NO IDEA what you mean by item #1, but to get the value of a form item you use getField. Please refer to the Adobe JavaScript API Reference for more information.

Page numbers in JavaScript start at zero. They also are the just the sequential pages and not the renumbered pages. So if you have a 10 page document the frist page is zero and the last page is 9. To display the page numer in a message you add 1 and to navigate to a page from user input you subtract one. Acrobat forms use user selected form field names. So if you had a field formatted for numeric entry with a validation that the lowest number could not go below 1 and your field was name "SkipToPage", the "Mouse Up' action for the button could be:

// set the displayed page to the value of the "SkipToPage" value less 1
this.pageNum = this.getField("SkipToPage").value - 1;
