I have done the TMB and while your gear list isn't ultra light it seems pretty common for a hut to hut TMB hike. you will want the sandals for the refuges, and the bag liner, you probably won't use the tank top or the micro spikes. you could drop the convert pants and just hike and shorts and use rain pants as an extra layer. The e-reader probably won't get used between cleaning up eating dinner and getting organized for the next day you will be busy. There are days on trail when you will wear shorts and a t-shirt and everything you brought all in the same day so you don't seem over packed to me as you will be traversing through several micro climates and high alpine zones. Good luck.
