An earlier complaint with the software was that there wasn't a lot of documentation for the programs. The online help files tended to be written by computer geeks for computer geeks. However, a fast check of Amazon.com (see below) shows that there are now a number of how-to books from publishers, including a Dummies book.
If you don't have an unlimited budget for software (remember, you can't buy one copy of Microsoft Office and then install it on all the computers in your office) you should at least take a look at OpenOffice. It has a free trial period, after all, that lasts forever.
