Ending Junior Year Semester 1 with a 3.47 UW GPA... have I screwed up for T20's?

TBH, my advice is the same as it would be if you had hung onto the 3.8:
Build your list from the bottom up.

THIS. I can’t emphasize this enough. Starting with a top 20 or bust approach to colleges isn’t the best way to go. There are plenty of colleges where you can get a CS degree outside of the top 20. And really, some of those top 20 colleges are not well known for CS while colleges lower in the rankings are.
