For most problems I'd consult the Zelda Dungeon website. There you will find informative and detailed text walkthroughs, video walkthroughs, guides, side quest help, treasure help and much more for nearly every Legend of Zelda Game.
For Let's Plays I'd recommend Chuggaconroy, he is a completionist so you won't have to worry about missing any items or quests if you follow along. However he only has LPs for 3 Zelda games at the moment:
Links Awakening
Majoras Mask
Wind Waker
For glitch exploration I highly recommend you check out EggBusters.
Wind Waker
Ocarina of Time
Ocarina of Time Redux
Twilight Princess
Twilight Princess Revisit Part 1
Twilight Princess Revisit Part 2
Zelda Dungeon: A Zelda Guild
