If Lamphear's still there take his Military History courses, likewise for Gwyn Morgan's Roman Emporers.
Take Death from Twombly and Trimble's writing courses.
Take anything from Cafarelli (in Math) - you're guaranteed an A if its an udergrad course and seeing the maestro (Luis "Mathematical Fists of Fury" Cafarelli) is awe inspiring.
Take Topology (1 or 2) from Starbird himself. Likewise get a Vick and a Guy class. Hamrick is an excellent Engr. Calc. teacher.
If Kermit is still there take his Rap & Rhetoric class. If McGlade is there take his Economics of Art course - or any S. Amer. eco. course he's giving (he is THE expert). Take any computational eco. from Kendrick - also considered "the best". (For that matter learn your basic Freeman models from Freeman and your Smith models from Smith).
You missed your chance for Esdjer Dijkstra - tough luck; Richards is good for Haskell. Take the course on Beer.
Take Rory Coker's "Pseudoscience" - remember to show up (you pass or fail on attendance alone). Take biochem from Brent Iverson (if you're Nat. Sci. try to get into Dean's Scholars for the seminars).
Arbogasts Numerical Analysis course is dry but can be entertaining :
Take intro. to philosophy from THE Bob Solomon - make sure to get pizza/beer et al. =) from him at the end of the year.
p.s. if you can stomach it and have the time Stroustrup is teaching at TAMU about 90 min. up the road from you.
