I'm a rising 2L at UT, just stumbled upon this site today.
Last Fall is a hazy memory, but I think first day assignments were posted on the Freshlaw site. They went up either during orientation or right before. I do remember that we only had a couple of days to read, but the first day assignments were pretty light and easy.
As for class syllabi, a lot of profs will post them up on Blackboard, but I'm not sure that that will be available to you before classes start. I think for most of (maybe all) of my classes, the profs handed out the syllabus on the first day.
Again, sorry for the lack of detail, but right now it seems like a really long time ago. Don't worry, you will get your assignments eventually, and you will have plenty of time to complete them.
Welcome to UT Law.
