I know how much more practical Reflection is than Color when it comes to mapwalking, however I've heard a few times that Reflection upped your chances of getting banned. Is that true?
If you use it stupidly, yes, but that same concept goes for all of them really. As long as you use tolerances and don't constantly click the same spots over and over then you should be fine.

What is the current state of TPA walking? Can a complex script be written strictly out of it?
Work's great if you know what your doing. This is my preferred method actually. I have written walking for MSI using only TPA's, as well as the walking for my Yew cutter, and the majority of my old scripts too.
Just get a proper understanding of some sorting methods, multi dimensional arrays (not necessary, but definitely helps) and the different ways of looping and you can walk most anywhere.
I would be glad to help you out sometime if you want.
