Enough materials?

Actually u already have more than u should use. Remember it is not about how many books u have covered, but rather how effectively u have utilized them -- the quality matters and not the quantity. Moreover, there is high risk of getting "too much" material all jumbled up and getting confused. Stick to official material and KAP and Princeton. From ur list I would rather delete Prof Dave's and Nova's as I think they are bad overall. Also, if possible, get OG 11th ed and not 10th. Also if u plan to study KAP 2005, then take out KAP 800, most of the questions on this are repeat from KAP 2005 and KAP workouts, hence not worth an extra dime.

Focus and approach ur prep with confidence. Keep ur prep time max to
3 months and u will be fine ! Good luck !
