Re learning form examples, just import them and look at the script. There are plenty of my objects that interact with web pages so you can see how they work.
Re Excel - starter here, but beyond that you need to look at the object model to interact (http://msdn.microsoft.com/library/en-us/dv_wrcore/html/wrconExcelObjectModelOverview.asp)
Dim objExcel
Dim objWorkBook
Set objExcel = CreateObject("EXCEL.APPLICATION")
Set objWorkBook = objExcel.Workbooks.Open("C:\test\test.xls")
objWorkBook.SaveAs ("C:\test\test2.xls")
objWorkBook.Close True
Set objWorkBook = Nothing
Set objExcel = Nothing
