Jenna Moreci on YouTube offers good advice and she's funny. Just a warning, she uses foul language, lol.
5,000 Words Per Hour by Chris Fox. This book is great for helping you improve writing speed. The title isn't literal, just a guide on upping word count. Say you only write 500 words a day, the guide could help you double that. His other writing books are good too, I really like Lifelong Writing Habit. The others are geared toward self-publishing so if you're interested in that you could check those out too.
The Emotion Thesaurus by Angela Ackerman and Becca Puglisi. Good resource to help you convey characters's emotions without explicitly saying things like: "She was mad." So more along the lines of: "Her hands balled into fists as her jaw clenched." They have other books too, but I haven't read those.
I've heard How to Write Dazzling Dialogue by James Scott Bell is good, but I haven't read it yet.
The NaNoWriMo website has some writing resources you could check out. Here.
