Attention students…you are eligible to purchase discounted software. First, the UT bookstore (College & St. George) sells versions of all major software at low rates - just bring your student card. Second, if you need MS Office, last year some students were doing their own price comparisons, and found http://www.microsoft.com/student/discounts/theultimatesteal-ca/default.aspx - which is only $64 Cdn for MS Office but includes "extras" including access, onenote and others. It was a little cheaper than what you get at the UT bookstore. The one catch is that Microsoft asks for your university email.
If you are looking for web authoring software, consider the open source option of NVU instead of DreamWeaver, available at http://net2.com/nvu/download.html
